LEADING THE DAY:

Former Vice President Joe Biden Joe BidenCast of 'Parks and Rec' reunite for virtual town hall to address Wisconsin voters Biden says Trump should step down over coronavirus response Biden tells CNN town hall that he has benefited from white privilege MORE is in position to stretch his delegate lead over Sen. Bernie Sanders Bernie SandersMcConnell accuses Democrats of sowing division by 'downplaying progress' on election security The Hill's Campaign Report: Arizona shifts towards Biden | Biden prepares for drive-in town hall | New Biden ad targets Latino voters Why Democrats must confront extreme left wing incitement to violence MORE (I-Vt.) as voters in six states head to the polls tonight.

Biden is headed for a blowout victory in Mississippi, which should continue his run of stronger performances in the deep south, where black voters have lifted him to victories.

The former vice president is also leading big in polls of Missouri, where Sanders only narrowly lost to Hillary Clinton Hillary Diane Rodham ClintonHillicon Valley: FBI chief says Russia is trying to interfere in election to undermine Biden | Treasury Dept. sanctions Iranian government-backed hackers The Hill's Campaign Report: Arizona shifts towards Biden | Biden prepares for drive-in town hall | New Biden ad targets Latino voters FBI chief says Russia is trying to interfere in election to undermine Biden MORE in 2016.

The big prize of the night is in Michigan, and polls show Biden up from anywhere between 8 to 24 points.

There are 125 delegates up for grabs in Michigan, more than one-third of tonight's total delegate haul. A victory in the Wolverine State could give Biden an air of inevitability.

Sanders has been hunkered down in Michigan, looking for some of the magic that propelled his unlikely 2016 challenge to Clinton. That year, polls showed Sanders down by 20 points in Michigan heading into Election Day, and his stunning victory in Michigan completely reshaped how people viewed the primary contest between him and Clinton.

Can he do it again?

It looks like an uphill battle. Biden has opened up about a 20-point lead nationally over Sanders, a massive shift of support that has unfolded over the past 8 days.

Sanders suddenly looks vulnerable even in the Western states he won big in 2016 that will vote on Tuesday night.

Polls show Biden and Sanders running about even in Washington, Idaho and North Dakota. Sanders won all those states by 40 points or more in 2016.

FROM THE TRAIL:

Coronavirus concerns have spread to the campaign trail as voters look to make their voices heard at the ballot box in Tuesday's contests and next week on March 17.

Both Sanders and Biden cancelled rallies planned to be held in Cleveland amid growing concerns over the virus.

In recent days, the candidates had continued to make campaign stops and hold get out the vote events. But it's clear now that the virus is a point of concern for the candidates.

It's unclear whether this was the work of staffers or attendees, but the entrance to Biden's event in Detroit last night was stocked with hand sanitizer.

The outbreak could also impact voter turnout in a number of upcoming contests. The Hill's Rebecca Klar reports that Washington State officials are hoping the Washington Democratic Party's decision to conduct its primary by mail-in and drop-off ballots rather than with caucuses, as in previous election cycles, reduces the risk of spreading the virus.

Meanwhile, Biden and Sanders have given a preview of how they would respond to a similar crisis as president, The Hill's Julia Manchester reports. Biden has honed in on his time as vice president, citing his experience combatting the 2014 Ebola outbreak. Sanders has used the opportunity to tout his own Medicare for All proposal, saying under his administration every American diagnosed with the virus would have access to a doctor and a vaccine.

Biden is picking up the support of labor leaders and unions, including some that endorsed Sanders in 2016, The Hill's Alex Gangitano reports. The endorsements reflect both the unease with Sanders that some in the labor movement feel, as well as a sense that Biden has the momentum in the Democratic primary race that he'll need to clinch the nomination.

Elizabeth Warren Elizabeth WarrenWarren, Schumer introduce plan for next president to cancel ,000 in student debt The Hill's 12:30 Report - Presented by Facebook - Don't expect a government check anytime soon No new taxes for the ultra rich — fix bad tax policy instead MORE (D-Mass.) to endorse Sanders for the Democratic presidential nomination, arguing that he would do the same for her if the shoe were on the other foot, The Hill's Rebecca Klar reports. Warren, who ended her campaign last week following disappointing finishes on Super Tuesday, has said that she will not endorse in the race right away, though Sanders would be a clearer ideological fit for her support.

ONE FUN THING:

While scientists are hard at work developing a potential vaccine for the coronavirus, former presidential candidate and Sanders supporter Marianne Williamson Marianne WilliamsonMarianne Williamson discusses speaking at People's Party Convention Fewer people watched opening night of Democratic convention compared to 2016 Marianne Williamson: Democratic convention 'like binge watching a Marriott commercial' MORE has another method in mind to deal with the outbreak.

Williamson posted an 11 minute "coronavirus mediation" to her IGTV account on Tuesday. She wrapped the video with a deep breath and told viewers to "go wash your hands, thanks."

Not everyone is into meditation, but, coronavirus outbreak or not, you can't go wrong with washing your hands.

We'll see you tomorrow with a breakdown of Super Tuesday Part 2!

In the meantime, wash your hands!
