The Michigan Democratic Party's rules committee voted to hold its presidential nominating caucus on Jan. 27 next year, the same day New Hampshire is expected to hold its presidential primary.

That would violate national party rules, which say only Iowa and New Hampshire can hold their presidential nominating contest before Feb. 3.

The date could be changed when the 400-member Michigan Democratic State Central Committee meets April 26.

"Nothing is set in stone. It's a draft plan," state Democratic Chairman Melvin "Butch" Hollowell said Sunday evening after the rules committee meeting.

New Hampshire Democratic Chairwoman Kathy Sullivan said Monday that she hadn't decided yet whether to ask presidential candidates to boycott Michigan if the state decides to hold its caucuses on the same day as the New Hampshire primary.

"There are a lot of more important things going on in the world than the efforts by a few people to change the rules of the game," Sullivan added. "We'll see where we are in 30 days."

DNC Chairman Terry McAuliffe has said Michigan risks having the convention refuse to seat a large portion of its national convention delegates if it defies the rules. He sent a letter last week to the state's Democratic Party leaders urging them to hold their caucuses on Feb. 7.

Michigan Democratic leaders supporting the Jan. 27 date say it's time for a state that's more diverse and representative of the rest of the country to play an early role in choosing the Democratic nominee.
