Trump and Biden win Michigan primaries

President Joe Biden and former President Donald Trump scored decisive wins in their respective Michigan primaries on Tuesday, though for each, it remains to be seen just how large their victories were.

Trump continues to face a faction of Republicans who refuse to back his candidacy despite his chokehold on the nomination. Biden was confronted with a protest movement urging Democrats to vote “uncommitted” in the primary over his handling of the Israel-Hamas war. Early returns showed that “uncommitted” was poised to easily garner more than 10 percent of the vote statewide.

The fissures in both parties raise questions about how each candidate will fare in this critical swing state.

For Biden, the main political threat has come from progressives and like-minded voters. A coalition of Arab-American leaders in Michigan organized a push for the "uncommitted" vote through the “Listen to Michigan” campaign. The effort involved organized protests and phone-banks, reaching tens of thousands of voters, with an aim to pressure the president into supporting an immediate cease-fire in Gaza.

For Trump, the threats have been both political and legal in nature. His unbroken swing of early state victories has given him a commanding position in Republican politics. But he remains embroiled in court cases stemming from his business practices and his time in office. He is also, like Biden, unpopular with the public at large. Trump also continues to slash at primary rivals — past and present — even after they have ceased to threaten him politically.

Trump has taken steps in recent days to claim more direct operational control of the party, including installing loyalists at the Republican National Committee.

Biden, for his part, dispatched top administration officials and allies in Congress to Michigan to talk with community leaders about the Israel-Hamas conflict. The state’s governor, Gretchen Whitmer, has encouraged Democrats to vote for the president even as other Democrats — including Rep. Rashida Tlaib (D-Mich.) and former Democratic presidential candidate Beto O’Rourke — pushed voters towards the “uncommitted” line.
