This happens both ways all the time. You don't think faux liberals were out punching the ticket for Mccain this time? Give me a break, this guy was dead, had no money and was ready to pack it in. The dems in droves saw this and figured why not shake things up and push a liberal repub up to piss of the core conservative bunch. To that the dems did a great job. Too bad they've now cause major strife in their own party. If they hadn't you probably would have seen a more drawn out repub contest and Hillary would have wrapped it up on Super tuesday, but no they got cute and the Clinton machine starting pushing for crosssovers to get Mccain elected.
