So Florida is not going to revote. Why? Apparently, they don't want to.

Meanwhile, there's a giant hurdle in Michigan, as my colleague Marc Ambinder reports. A lot of Democrats voted in the Republican primary, since Obama wasn't even on the Democratic ballot. It's not sure-fire that they would have broken disproportionately for Obama, but that seems like the way to bet.

This seems like a pretty huge blow for Hillary; she'll have an uphill battle getting those delegates seated. I'd imagine there will be some sort of compromise where the superdelegates get seated, but the regular delegates are shut out.
