  • With just one state left to report, former Vice President Joe Biden is dominating Sen. Bernie Sanders of Vermont across the board in the six March 10 Democratic presidential primary elections.
  • Biden has clinched huge victories in Mississippi, Missouri, Michigan, and Idaho. Michigan, which Sanders won in his 2016 presidential bid, was the biggest delegate prize of the night.
  • Sanders has won the North Dakota caucuses, his first victory of the March 10 contests. We’re still awaiting full results from the Washington primary, which was conducted by mail.

Here’s how Democrats will elect their presidential nominee over the next several months

What’s at stake in the primary?

The six states with elections Tuesday collectively allocate 352 delegates to the convention, making up about 9% of all delegates awarded throughout the Democratic primary contest.

  • Michigan allocates 125 pledged delegates to the convention, making up 3.5% of the total allocated. Polls close in most of the state at 8 p.m. ET. In four of Michigan’s Upper Peninsula counties located in the Central time zone, polls closed at 8 p.m. CT (9 p.m. ET).
  • Mississippi allocates 36 pledged delegates to the convention. Polls closed at 7 p.m. CT (8 p.m. ET).
  • North Dakota allocates 14 pledged delegates to the convention. Polls in the state’s firehouse caucuses closed at 7 p.m. CT (8 p.m. ET).
  • Missouri allocates 68 pledged delegates to the convention. Polls closed at 7 p.m. CT (8 p.m. ET).
  • Idaho allocates 20 pledged delegates to the convention. Polls closed at 8 p.m. Mountain Time (10 p.m. ET).
  • Washington, which allocates 89 pledged delegates to the convention, conducts its elections entirely by mail. Voters must either mail in a ballot postmarked by Election Day or drop off their ballot in person in their county elections office no later than 8 p.m. local time on the day of the election.

Democrats allocate most of their pledged delegates proportionally by legislative district, in addition to allocating at-large and PLEO (party leader and elected official) delegates based on the statewide vote breakdown.

While delegates are allocated proportionally, in nearly every state the minimum threshold to earn delegates is 15% of the vote. This means candidates must break 15% of the vote at either the congressional district or state level to earn any delegates.

Now that the race is narrowed down to just two major candidates, both Biden and Sanders are now likely to pass the delegate threshold in the coming states.

Tuesday’s primaries come a week after Biden’s blowout victory on Super Tuesday, in which he won 10 out of the day’s 16 electoral contests outright and far surpassed Sanders in national pledged delegates.

Biden winning key states like Mississippi, Missouri, and Michigan, which collectively account for 229 pledged delegates, gives him another huge boost in his quest to the nomination and makes Sanders’ path to victory even narrower.

Decision Desk HQ in partnership with the University of Virginia Centre for Politics projects that Biden has so far won at least 163 pledged delegates from Tuesday night’s primaries compared with 97 for Sanders.

Who did the polling say was ahead?

FiveThirtyEight’s average of the latest polling data showed Biden significantly advantaged in several key states voting Tuesday, including ones that Sanders handily carried in 2016.

The day before the election, Data for Progress released polls showing Biden leading Sanders by a massive 55-point margin, 77% to 22%, among likely Mississippi Democratic primary voters and also ahead by 4 percentage points in Idaho, where the former vice president held the support of 51% of likely Idaho Democratic primary voters compared with 47% backing Sanders.

Biden also led the latest polls by huge double-digit margins in Michigan and Missouri, two states Sanders either narrowly won or lost to Hillary Clinton in 2016 by margins of 2 percentage points or less.

In Washington state, where Sanders beat Clinton by a margin of 45 percentage points in the state’s 2016 caucuses, Biden also narrowly leads the most recent polls entering Tuesday’s elections.

While there isn’t any recent polling data from North Dakota, FiveThirtyEight’s primary election forecast used other factors for its projections including the results of this year’s primary so far, previous presidential primaries, candidates’ fundraising performance and elite support, and individual states’ voting histories and demographic.

According to FiveThirtyEight’s forecast, Biden was projected to win the most pledged delegates in all six states voting Tuesday. Biden had the greatest chance of winning Michigan, Missouri, and Mississippi and was also projected to win the most delegates in Idaho, North Dakota, and Washington.
