I don't think that she'll drop out or be pulled. That would be a total meltdown of McCain's campaign. I don't think they could recover from that. It would royally piss off the christian right and the rest of the party would just lose what little enthusiasm they now have. Who would he then pick? Romney is already ticked off and Lieberman is a no go as far as the right wing is concerned.

Sure would like to she her drop off the ticket though!

edit:

Just came across this...
