LEADING THE DAY:

TOMORROW: Democratic contenders 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.) and 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 will go head-to-head for the first time in the Democratic primary tomorrow as voters in Michigan, Missouri, Mississippi, North Dakota and Washington state make their voices heard.

The contests, which has been dubbed "Super Tuesday Two," will mark a critical moment for Sanders following Biden's rise on Super Tuesday last week. Both of the candidates have been focused on Michigan, in particular.

Sanders took political watchers by surprise in 2016 when he bested 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 the Great Lakes State, but now he trails Biden in a number of Michigan polls. Sanders is working to close the gap. The senator has added more stops in Michigan, and he is also touting a big endorsement he received from Rev. Jesse Jackson, who appeared with him on the campaign trail in the state.

Sanders is in desperate need of a good night to regain momentum and show that he is a viable candidate going forward. The map on March 17, when Florida, Arizona, Illinois and Ohio go to vote, is already more favorable to Biden, meaning Sanders will need to soften any potential blow.

Meanwhile, a big outside factor is being thrown into the primary -- this time in the form of COVID-19, more commonly known as the coronavirus. The virus, so far, has hit Washington state the hardest, raising the question of how it will affect voter turnout. However, the northwestern state votes by mail, which will likely alleviate the impact of the virus. Looking ahead to March 17 though, the virus could affect voting in Florida, a highly populous and transient state.

It's too early to tell if there will be an impact yet, but in the meantime, wash your hands!
