Michigan primary updates: Biden, Trump projected to win respective primaries, inching closer to November rematch

President Joe Biden and former President Donald Trump won their respective parties’ presidential primary in Michigan Tuesday night, ABC News projects.

Polls were open from 7 a.m. to 8 p.m. local time.

Early voting in the state’s presidential primary occurred from Feb.18 through Sunday.

Vote-by-mail absentee ballots had to be received by a local elections clerk by 8 p.m. on Tuesday.

A separate state primary for U.S. representative and state legislative seats will be on Aug. 3.

While both Democratic and Republican presidential primaries are being held in Michigan, delegates to the Republican National Convention will not be bound wholly based on Tuesday’s primary results.

The GOP primary results determine 16 delegates. The remaining 39 of Michigan’s 55 Republican delegates will be awarded based on a resolution to be determined at a subsequent state party convention as well as the state party’s congressional district caucuses.

All 117 of Michigan’s Democratic delegates will be awarded based on the primary election results on Tuesday.

State significance

Michigan has become a closely contested swing state in recent presidential elections, having swung between the Democratic and Republican candidates in the last three elections.

After decades of voting for Democrats, the state narrowly voted for Republican Donald Trump in 2016 and then switched back to Democrat Joe Biden in 2020. Michigan was also an epicenter of baseless election conspiracy theories during the 2020 election, which received national attention.

Both President Biden and former President Trump have faced recent headwinds in the state.

Muslim and Arab American leaders in Michigan have launched efforts to campaign against voting for Biden in the 2024 election in protest of his policies regarding the Israel-Hamas war.

Trump’s 2024 candidacy had also been challenged in the state under the 14th Amendment because of his actions around Jan. 6, but the state Supreme Court rejected that.
