As the window for a potential revote in Michigan becomes ever smaller, a team of rich Democratic donors are promising to front the money for a new primary in a last-ditch effort to save the contest, USA Today reports. And to no one's surprise, those donors largely back one candidate over the other, demonstrating again just how crucial a revote is to Hillary Clinton's chances of winning the nomination.

New Jersey Governor Jon Corzine and Pennsylvania Governor Ed Rendell, both major Clinton supporters, spearheaded the initiative to put together donors willing to fork over the $12 million for a new contest, and Corzine is one of the ten people listed as willing to guarantee the money will be there. The former Goldman Sachs chief spent $60 million of his own money to get elected to the governorship and is worth somewhere north of $250 million.

Corzine is joined by several other prominent Clinton backers, including Haim Saban, Bernard Schwartz, Roger Altman and John Catsimatidis. While all ten of the donors have given to Clinton's campaigns for Senate or the White House, two are less involved in the campaign, as lawyers John Eddie Williams and Peter Angelos have stayed out. Angelos' name might sound familiar; the prominent trial attorney now owns the Baltimore Orioles baseball team.

The Obama campaign has been naturally suspicious of any revote, and now that Clinton donors are offering the cash to run it, they've become even louder in their protests. Spokesman Bill Burton told USA Today the promise, contained in an open letter to Michigan Governor Jennifer Granholm, is "even more evidence that Clinton is willing to do absolutely anything to get elected."

Though they were trying to help, the ten donors may have unintentionally doomed Michigan's hopes of holding a revote at all, allowing the Obama camp to slam the window shut once and for all.
