Biden projected to win Michigan for biggest prize Tuesday
Former Vice President Joe Biden is projected to beat Vermont Sen. Bernie Sanders in Michigan on Tuesday, according to Associated Press voter surveys.
The projected win, coming as polls closed in Michigan, solidifies his lead in the Democratic primaries after turning around his campaign in South Carolina and a majority of Super Tuesday states.

Michigan's 125 pledged delegates gave Biden the biggest prize among six state contests Tuesday. His victory was expected, after a Monday poll by EPIC-MRA for the Detroit Free Press showed a healthy lead - 51% to 27% -- against Sanders.
The win extended Biden's lead against Sanders for the Democratic nomination to challenge President Donald Trump. Both candidates looked to Michigan to signal how they would perform across the industrial Midwest, before Ohio and Illinois vote March 17, Wisconsin on April 7 and Pennsylvania on April 28.
Sanders, who narrowly won Michigan against eventual nominee Hillary Clinton in 2016, argued that union workers would support him because of Biden's support for "disastrous" trade deals. Sanders blamed the loss of millions of good-paying jobs on the North American Free Trade Agreement with Canada and Mexico, and on normalizing trade with China, under what was called Permanent Normal Trade Relations.
But Biden promoted the auto industry bailout that began under President George W. Bush and expanded at the start of President Barack Obama's administration. The auto bailout helped General Motors and Chrysler weather the Great Recession - and the companies repaid the federal government for the help. By the end of 2018, $63 billion was repaid, the government received $8.4 billion in income and about $16.6 billion was written off as a loss, according to a Congressional Research Service report.
Michigan Gov. Gretchen Whitmer and former Gov. Jennifer Granholm each endorsed Biden, saying he was the official who championed the auto industry and the millions of Midwest jobs that depend on it.
"Michigan is not going to forget," Granholm told CNN. "We were on our knees and Joe Biden picked us up and carried us on his shoulders."
Biden remains favorite among African American voters
Former Vice President Joe Biden's projected early wins Tuesday in Mississippi and Missouri continued his strong showing against Vermont Sen. Bernie Sanders among African American voters.
Biden outpolled Sanders on Tuesday with black voters by 84% to 13% in Mississippi and 69% to 28% in Missouri, according to polling data.
Biden, who served eight years with the first black president, Barack Obama, has said he owes his comeback to black voters. After losing the first contests in Iowa, New Hampshire and Nevada, Biden pinned his hopes on South Carolina, where Biden won big with the Democratic primary electorate 60% black voters.
On Super Tuesday on March 3, Biden swept southern states. He beat Sanders among black voters by 71% to 16% in Virginia, 62% to 17% in North Carolina, 72% to 9% in Alabama and 53% to 20% in Tennessee, according to exit polls.
Age also played a role. Sanders, a Democratic socialist, built his revolutionary campaign on younger voters. The candidates divided voters who are 18 to 29 years old in Mississippi, with Biden supported by 48% and Sanders by 44%. But Sanders beat Biden among younger voters in Missouri by 76% to 19%.
But older voters sided with Biden. Biden also beat Sanders among voters at least 65 years old, by 89% to 9% in Mississippi and by 77% to 17% in Missouri.

Joe Biden is projected to win Mississippi and Missouri
Former Vice President Joe Biden is the projected winner of the Mississippi and Missouri primaries, based on AP's analysis of voter surveys.
Biden and Sanders each campaigned in Missouri, which has 68 pledged delegates. Biden held rallies Saturday in St. Louis, where he said that "we're going to unite this party and unite this country," and Kansas City. Sanders rallied supporters in St. Louis on Monday, telling them they provided the enthusiasm to defeat President Donald Trump.
But Biden's win in Missouri was expected because an average of polls through Monday showed him ahead with nearly 52% support, compared to 31% for Sanders, according to a summary by FiveThirtyEight.com.
Biden was looking to extend his winning streak among states with large African American populations, promoting his endorsements Monday from former primary rivals: Sens. Kamala Harris of California and Cory Booker of New Jersey.
Biden found the strongest support in the St. Louis area and in mid-Missouri, while Sanders found backing in the northern and southern parts of the state. Among the Democrats on the state's congressional delegation, Rep. Emanuel Cleaver endorsed Biden and Rep. Lacy Clay endorsed Harris before she dropped out and hadn't announced a new selection by Monday.
Biden's win in Mississippi was expected because he led an average of polls through Monday with nearly 67% support, compared to 22% for Sanders, according to a summary by FiveThirtyEight.com.
Sanders was scheduled to visit Jackson on Friday, but decided instead to focus on Michigan.
Biden spoke at a Jackson church on Sunday and then hosted a rally at Tougaloo College with actress Vivica A. Fox and former Massachusetts Gov. Deval Patrick.

First polls have closed in three states
Voting has ended in the first three of the six "Junior Tuesday" contests that could go far in determining whether Bernie Sanders can blunt the momentum Joe Biden rode during the Super Tuesday primaries a week ago.
Voters participating in primaries in Mississippi and Missouri and caucuses in North Dakota had until 8 p.m. ET to cast ballots. Most polls in Michigan close at 8 p.m. ET, except four counties that close at 9 ET, followed by Idaho and Washington, both at 11 p.m. ET.
Biden is leading with 670 delegates to 574 for Sanders. To win the nomination, a candidate must amass 1,991 delegates. Michigan is the biggest prize with 125 delegates, followed by Washington (89), Missouri (68), Mississippi (36), North Dakota (14), and Idaho (13).
Another 13 delegates are available Tuesday from ballots cast by Democrats living abroad.

DNC and CNN announce no live audience for Sunday's debate amid coronavirus fears
The Democratic National Committee announced Tuesday night that there will be no live audience at Sunday's debate taking place in Arizona.
"At the request of both campaigns and out of an abundance of caution" amid coronavirus fears.
CNN, the network co-hosting the debate between Joe Biden and Bernie Sanders, said their "top priority is the safety of our employees and community members. This extends to guests planning to attend or cover our debate on March 15."
The network also said that there will not be a press filing center or spin room for reporters covering the campaigns.

As of Monday afternoon, Arizona's count of new-coronavirus cases was presumed to be six, but more tests were pending, according to the Arizona Republic.
To date, 56 Arizonans have been tested for infection and 44 have had negative results. Six cases of the disease, also known as COVID-19, were either confirmed or presumed positive, and six were pending, meaning there could be more cases announced soon.
Sunday's debate will be the first time Biden and Sanders are set to appear on stage after Biden's strong Super Tuesday showing in which Biden took a double-digit delegate lead over Sanders for the party's presidential nomination.
Worldwide, the novel coronavirus has infected more than 113,000 people and left 4,000 dead. In the United States, nearly 1,000 people have tested positive, and around 30 people have died.
Coronavirus prompts new polling places to protect elderly
Voting-rights officials said the coronavirus outbreak has had a cascading effect on the primary season, with election officials in states such as Ohio and Illinois that vote March 17 beginning to shift polling places away from senior-citizen homes.
Ohio officials at 88 boards of elections worked to relocate polling sites at residential senior facilities, according to Kristen Clarke, president of the Lawyers Committee for Civil Rights Under Law. For example, Franklin County will have 16 different polling places, she said.
"Those 11th-hour polling changes impact over 21,000 voters," Clarke said on a call organized by Election Protection, a coalition of voting-rights groups that monitor election problems. "Those are all voters who need to be fully notified about the polling site changes to assure that their right to vote is not compromised next Tuesday."
The changes raise concerns about potentially discouraging senior citizens from voting if they have trouble finding or traveling to new polling places.
"These 11th-hour polling site changes are also happening in Illinois, where they are moving out of senior citizen centers and finding new locations," Clarke said.
Health officials have warned that the elderly are more at risk of complications from coronavirus. The leading Democratic candidates - former Vice President Joe Biden and Vermont Sen. Bernie Sanders - each canceled campaign rallies in Cleveland because of concerns about coronavirus. Ohio Secretary of State Frank LaRose issued call for more poll workers. And in Florida, election officials in Palm Beach County reported an uptick in mail-in ballots and a dip in poll workers. Officials are working to stock polling places with cleaning supplies, she said.
"All of these changes illustrate the impact that the coronavirus is having on this election season and underscores the need for states to strengthen their level of preparedness," Clarke said. "Between last week and today's primary election, we've observed a cascading effect that the coronavirus has had on this electoral season."
Pro-business group tries to stoke resentment among Sanders' supporters
The Club for Growth is a pro-business lobby dedicated to "defeating big-government politicians and replacing them with pro-growth, limited government conservatives."
And yet the group's political arm announced Tuesday it was releasing a digital ad sympathetic to Vermont Sen. Bernie Sanders, a self-described socialist Democrat whose advocacy for Medicare-for-all, the Green New Deal and a steep wealth tax has put him at odds with corporate America.
The ad, titled "Remember," lays out what it calls the "Democratic Establishment's war on the presidential campaign of Senator Bernie Sanders." The 30-second spot paints Sanders as the victim of a campaign by Democratic Party leaders who will "do anything to stop Bernie," a refrain many of the senator's supporters often repeat.
"Now the billionaires are propping up Joe Biden … because they own him," the ad goes on to say. "Don't let them steal it. And if they do - remember in November."
The ad will be seen on digital platforms in four key states holding primaries March 17: Arizona, Florida, Illinois, and Ohio.
The ad comes as Biden is leading Sanders in what has become a two-person contest for the Democratic presidential nomination. Most analysts say - and polls generally confirm - that Biden has a better chance than Sanders of defeating President Donald Trump.

Long lines in Michigan
Voting-rights advocates reported few systemic problems Tuesday, but long lines were seen at college campuses in Michigan where same-day registration is available.
"Michigan has some extremely long and frankly completely unacceptable lines including on two of our major flagship universities," said Sharon Dolente, voting rights strategist for the American Civil Liberties Union in Michigan.
Lines of one to two hours were reported at the University of Michigan, Michigan State and at Western Michigan University in Kalamazoo, she said.
The state changed its rules to make it easier to vote, including allowing registration until polls close at 8 p.m. Dolente said election officials failed to anticipate how many students would turn up and the capacity wasn't available to process them quickly.
"That's unacceptable, in my opinion," Dolente said during a call organized by Election Protection, a coalition of voting-rights groups that monitors problems on election day.
Her group is attempting to deputize poll workers, to get voters processed. She worried at 6:30 p.m. Eastern that lines might grow longer before the polls close.
"I assume that that line is going to keep growing because right up until 8 p.m. voters are showing up at polling locations," Dolente said.
Voters in Missouri, Michigan, and Mississippi see Biden as more electable, AP VoteCast polling says
As voters head to the polls for today's primaries, voters in Michigan, Missouri, and Mississippi saw former Vice President Joe Biden as more electable than Sen. Bernie Sanders, I-Vt, according to VoteCast polling by the Associated Press.
About 80% of Democratic primary voters in Michigan and Missouri thought Biden could beat Trump, and about 90% in Mississippi thought he could win, whereas about two-thirds of voters in all three states saw Sanders as able to beat Trump. Former Secretary of State Hillary Clinton won Mississippi and Missouri in 2016, though Sanders won Michigan then.
It also appeared that fewer progressive Democrats turned out in all three states. Majorities of voters in all three states described themselves as "moderate" or "conservative." Seventy-two percent of Mississippi Democratic voters described themselves that way, 61% of Missouri Democratic voters described themselves the same way, as did 62% of Michigan Democratic voters.
Voters in Michigan and Missouri also expressed hesitancy about fundamental political change. A majority, or 53% of Democratic voters, in Missouri said they wanted the political system to be restored to how it was before Trump, as opposed to wanting to "fundamentally change" the system. Close to half, or 49% of Michigan Democratic voters, wanted a restoration to a pre-Trump system, and 49% wanted a fundamental change. In Missouri, 45% wanted a restoration of how the system was before Trump, and 52% wanted a fundamental change.
AP's VoteCast polling is conducted by NORC at the University of Chicago for seven days leading up to the primary, including as polls closed.

Biden, Sanders both cancel events due to coronavirus concerns
Former Vice President Joe Biden and Sen. Bernie Sanders both have canceled campaign rallies in Cleveland, Ohio, Tuesday night, citing public health and safety concerns.
Three cases of coronavirus have been confirmed in Ohio in Cuyahoga County, where Cleveland is located. As of March 10, there are 15 people being tested for possible exposure of coronavirus, also known as COVID-19.
"We are heeding the public warnings from Ohio state officials, who have communicated concern about holding large, indoor events during the coronavirus outbreak," the Sanders campaign said in a statement. "Sen. Sanders would like to express his regret to the thousands of Ohioans who had planned to attend the event tonight."
Sanders' event was going to be at Huntington Convention Center of Cleveland. The campaign also said all future "events will be evaluated on a case by case basis."
Biden campaign manager Kate Bedingfield tweeted a statement around the same time as Sanders' statement.
"In accordance with guidance from public officials and out of an abundance of caution, our rally in Cleveland, Ohio tonight is cancelled. We will continue to consult with public health officials and public health guidance and make announcements about future events," the tweet read.

All eyes are on Michigan as six states head to the polls
WASHINGTON - Welcome to Super Tuesday, Part 2.
Former Vice President Joe Biden and Sen. Bernie Sanders are separated by fewer than 100 delegates as six states - Idaho, Michigan, Mississippi, Missouri, North Dakota and Washington - head out to vote Tuesday.
Biden currently leads with 664 delegates while Sanders is in striking distance at 573. Rep. Tulsi Gabbard of Hawaii also remains in the Democratic primary, but has only amassed two delegates in the first 19 contests.
On the heels of last week's Super Tuesday, where Biden surpassed Sanders in the delegate race, both candidates have their eyes on Michigan.

More: How coronavirus could affect the six states slated to hold Democratic elections Tuesday
Michigan has 125 delegates up for grabs - the most of the day. And in 2016, Sanders had a surprising victory in the state over Hillary Clinton, who had been leading in polling.
But Biden got good news Monday with a Detroit Free Press poll showing him in the lead at 51% support and Sanders at 27%.
Washington, which has the second most delegates (89) being awarded Tuesday, could also be close, with Biden and Sanders neck and neck in recent polling. Sanders overwhelmingly won Washington in 2016, and he has won all of the Western states that have held contests so far this year.
Polls show good news for Biden in every state voting Tuesday
Polls released this week are good news for Former Vice President Joe Biden, who aims to expand his delegate lead over Sen. Bernie Sanders on Tuesday, when six states hold Democratic primaries.
Out of 18 polls on those six races that have been released since Sunday, none found Sanders ahead in any of the contests (though some found him within the margin of error).
Michigan, Idaho, Missouri, Mississippi, Washington and North Dakota are voting Tuesday. But the big prize is Michigan, which has the most delegates of all the states holding primaries Tuesday with 125. Sanders won the Michigan primary in the 2016 presidential race. But since Sunday, Biden has led Sanders in all of the eight Michigan polls released.

KC mayor says he was turned away from voting location
Kansas City Mayor Quinton Lucas said he was unable to vote because he wasn't "in the system" at his voting station.
"I made a video this morning about the importance of voting and then got turned away because I wasn't in the system even though I've voted there for 11 years, including for myself four times!" tweeted Lucas. "Go figure, but that's okay. We'll be back later today!"
The post featured a video of the mayor encouraging the state's residents to get out and vote on a ballot that includes the Democratic presidential primary.
Several people told the mayor, who is African-American, that he should not be OK with being turned away. "It's not okay, Mr. Mayor. A lot of people wouldn't be able to come back later. It's systemic and it's intentional," wrote one Twitter user in response to Lucas' tweet.
I made a video this morning about the importance of voting and then got turned away because I wasn't in the system even though I've voted there for 11 years, including for myself four times! Go figure, but that's okay. We'll be back later today! #Vote #KCMO pic.twitter.com/3mYNrO6jmC
- Mayor Q (@QuintonLucasKC) March 10, 2020
Lucas addressed their concerns in a later tweet, explaining he was "being Midwestern and passive."
"It's really not okay," tweeted Lucas, who said he would further investigate what happened.
"If the mayor can get turned away, think about everyone else.," he said. "We gotta do better."
Lucas tried to vote at Mount Pleasant Baptist Church, where he told The Kansas City Star he has cast his ballots since 2009. According to the Star, a poll worker searched Lucas' name using a utility bill but he didn't come up in the system.
Lauri Ealom, the Democratic director of the Kansas City Board of Elections, told the Star that the election worker had put the mayor's first and last name in the wrong fields.
Ealom said things were otherwise running smoothly at that voting location and that the mayor had so far been the only voter to be turned away.
