Because shes McCains running mate already! thats why Mitt is out of the picture lately.
You know, this has been the damndest cycle politically, so I really wouldn't put it past Hillary to gamble that she could actually get away with switching parties back to her original party -- if I recall correctly, she was a Republican (like her parents) in her earliest days. This whole election is becoming such a spectacular train wreck that I can really see it happening. Then ... who would you vote for, Republicans? Obama/Edwards (or whoever), or McCain/Clinton?
And which team you think Democrats would vote for? Hmmmmmmmmmmm?
Ah, it's all moot ... Dems are going to elect McCain anyway, Hillary or not, I think. Nobody likes Obama, but you know, a heck of a lot of Democrats don't like Hillary, either. It would be an interesting contest, then!
