Biden is enjoying a surge of momentum after his victories, and Sanders is looking to turn the contest around once again by defeating the former president in Michigan and other states. 

The two candidates also will battle it out in Idaho, Mississippi, Missouri, North Dakota and Washington, which combined will assign 352 pledged delegates on March 10. 

Here are what polls show in each of the states holding their nominating contests this Tuesday:

Michigan

Michigan will be the top prize on Tuesday, with its primary handing out 125 pledged delegates.

The two have swapped leads in recent polls, with a University of Wisconsin/State Journal poll showing Sanders with a 9-point lead and a Detroit News/WDIV-TV showing Biden ahead by 6 points. However, the poll showing Sanders ahead was conducted before the former vice presidents resounding wins in South Carolina and on Super Tuesday.

Biden has worked to rack up a number of endorsements of high-profile Michigan lawmakers, including Gov. Gretchen Whitmer, former Gov. Jennifer Granholm, Detroit Mayor Mike Duggan and several House members.

Biden also appears to have an edge among key demographics in Michigan the state has substantial amounts of African Americans and white suburbanites that helped power his Super Tuesday success.

While Sanders has overperformed among Hispanics and younger voters, Latinos make up a negligible amount of Michigans population and turnout among voters aged 18-29 has not spiked as the Vermont lawmaker has predicted.

Sanders narrowly won the Wolverine States primary over Clinton in 2016.

Mississippi

No recent polls have been conducted for the Mississippi primary race, but Biden is the heavy favorite given his support among African American voters.

Clinton routed Sanders by more than 65 points in 2016, and it wouldn’t be unthinkable to see a similar result this Tuesday.

Mississippis primary will award 36 pledged delegates.

Missouri

Biden holds a narrow 4-point lead over Sanders in Missouri in a new Emerson College poll conducted this week. The survey shows Biden and Sanders tied among white voters, but the former vice president holds a 14-point edge among voters of color.

Sixty-eight pledged delegates will be allocated in the states primary. Sanders narrowly lost the state to Clinton in 2016 by fewer than 2,000 votes. 

Washington

While Sanders has put his focus on Michigan, a key swing state contest in the general election, his best chance for a big victory might be here.

Sanders has leads in two recent polls in Washington state, though the states primary appears set to be more competitive than the surveys suggest.

The Vermont senator had a 6-point lead in an Elway Poll and a 5-point advantage in a January KING-TV/SurveyUSA survey. However, both polls showed former New York City Mayor Michael BloombergMichael BloombergThe Memo: Biden poised for gains in next waves of primariesWarren says a woman can still be president, ‘it’s just going to be a little longer’Women ask ‘if not now when?’ after Warren exits presidential raceMORE and Sen.

Bloomberg has since endorsed Biden, and Warren, who just dropped out Thursday, has said she has not decided if or who she will endorse. 

Another factor? Washington held a caucus in 2016, but has since shifted to a primary. 

Sanders won the caucuses in 2016 handily, but the primary could be more competitive.

The contest will allocate 89 pledged delegates, making it the second biggest haul of the March 10 contests.

Idaho

No recent polls have been conducted for the Idaho primary, which will allocate just 20 pledged delegates.

North Dakota

No recent polls have been conducted for North Dakotas caucuses, which will apportion just 14 pledged delegates. It is tied with Wyoming for hosting the smallest nominating race in the continental United States. 

Sanders won the state by nearly 40 points in 2016 over Clinton.
