The bill passed along party lines, with GOP lawmakers worrying that moving the primary up too soon would cost their party delegates under Republican National Committee rules.
But Amber McCann, a spokesperson for Democratic House leadership, says Republicans could always change their mind.
“I don’t believe there’s anything that will prevent the RNC from ensuring the delegates from Michigan are properly counted.”
Democrats need Republican support in the Senate for a procedural vote that would allow the bill to take effect in time for the 2024 primary.
Without it, remaining options become limited.
That's because by default, new laws only take effect 90 days after the legislative session ends, and under the current calendar, that would be after the new primary date.
