I mentioned here that the Michigan Democrats plan to mess with the Republican primary by voting for Huckabee because they have nothing better to do since their delegates are no longer in play as punishment for moving their primary up too early. But there are two other movements that may steal Democrats away from Huckabee. This one from Kos:

In 1972, Republican voters in Michigan decided to make a little mischief, crossing over to vote in the open Democratic primary and voting for segregationist Democrat George Wallace, seriously embarrassing the state’s Democrats. In fact, a third of the voters (PDF) in the Democratic primary were Republican crossover votes. In 1988, Republican voters again crossed over, helping Jesse Jackson win the Democratic primary, helping rack up big margins for Jackson in Republican precincts. (Michigan Republicans can clearly be counted on to practice the worst of racial politics.) In 1998, Republicans helped Jack Kevorkian’s lawyer – quack Geoffrey Feiger – win his Democratic primary, thus guaranteeing their hold on the governor’s mansion that year.
With a history of meddling in our primaries, why don’t we try and return the favor. Next Tuesday, January 15th, Michigan will hold its primary. Michigan Democrats should vote for Mitt Romney, because if Mitt wins, Democrats win.

And this one:

In Michigan, the uncommitted campaign is starting to pick up steam. That’s right, top Democrats in Michigan are out there urging residents to vote “uncommitted.”
[…]
“If ‘uncommitted’ draws at least 15 percent of the vote in a congressional district, delegates not bound to any candidate could be sent to the national convention, possibly enabling Obama and Edwards supporters to play a role in the nomination.”
There is even a newly formed group known as the Detroiters for Uncommitted Voters who plan to canvas door-to-door in the few days before next week’s primary, and ask people to not stay at home, or vote Republican but to vote … uncommitted.
The News reports that the Obama and Edwards campaigns are now urging their supporters to vote uncommitted, after earlier indications they would not do so. Election experts have said that if Clinton doesn’t get at least 60 percent of the votes cast, it would be a black eye for her campaign.

I think Michigan Democrats would make their voices heard loud and clear if they stuck it to Hillary (aren’t they upset over NAFTA and the loss of the manufacturing jobs?) and voted uncommitted.
