Palin reminds me of Jimmy Stewart in Mr. Smith goes to Washington. Fresh, energetic, a bit nieve but a quick study and ready to conquer the political machine. I believe she will do as you wish and shake things up in Washington. Biden certainly is not one to shake things up. I believe she's the type of person that would battle even the president if she found corruption and wrong doing and no amount of pier pressure or political strong arming will shut her up. I agree with you, however, that she'll not get the true liberal Clinton voters but I think she will appeal to many of the younger, 'soccer' moms more so that Obama. I for one know first hand. My girlfriend switched from Obama to McCain just because of Palin.

Obama is a crowd pleaser. Say anything. Do anything to win the crowd. Where and with whom will you find Obama standing? You'll find him which ever way the wind is blowing.
