March 10 primaries

The Michigan primary could have a big impact on the two-man race for the nomination.

This Tuesday, March 10, might not be quite as super as last Tuesday. But it’s still important: Six states — including the potentially decisive Michigan — will have the chance to weigh in on a dramatically reshaped Democratic presidential primary.

Idaho, Mississippi, Missouri, North Dakota, and Washington will all join Michigan in voting March 10, and voters will have a much-reduced Democratic field to choose from: Only former Vice President Joe Biden and Sen. Bernie Sanders have a real shot at the Democratic nomination for president at this point. (Rep. Tulsi Gabbard is technically still in the race).

Of those six, Michigan is the biggest prize, and not just because it has the most delegates on offer — though, with 125 delegates, that’s part of it. The state gave Sanders his signature win over eventual Democratic nominee Hillary Clinton in the 2016 primary. And if Biden can beat out Sanders there — which the FiveThirtyEight polling average for Michigan indicates is likely — then the rest of the primary calendar, with states like Florida and Georgia, looks increasingly difficult for the Vermont senator.

The New York Times also points out that the state will offer a preview of how candidates perform with key demographics that will be important come November:

Midwestern powerhouses like Michigan will test the candidates’ appeal among suburbanites, African-Americans and working-class white voters. If the race is not decided on Super Tuesday, this could be a line of demarcation.

Elsewhere, polling averages from FiveThirtyEight indicate Biden is in the lead in Mississippi and Missouri, and (narrowly) in Washington state.
