Basically, she wants the delegates to be seated in her favor with no "do-overs," although Obama wasn't even on the ballot in Michigan--a state where 40 percent of Democrats turned out to vote for "uncommitted" rather than her.
She told U.S. News in an interview:
"I would not accept a caucus. I think that would be a great disservice to the 2 million people who turned out and voted," Hillary said. "I think that they want their votes counted. And you know a lot of people would be disenfranchised because of the timing and whatever the particular rules were."Caucuses in this election have so far benefited Obama, as the process requires more time and enthusiasm on behalf of the voters to conduct.
