In a word, it says he's a grown-up.

Has anyone heard of one person, just one, that has decided to vote Obama-Biden based solely on the selection of Biden as VP?
Palin is the politically perfect candidate for this particular election. After a couple of years as VP, especially if she functions in the manner of a Cheney, i.e. has a real job, she will be quite ready to be the next president after McCain. Right now it is my fantasy to see the primary election in 2016 or, God forbid, in 2012 be a contest between Palin and Jindal or between the two on one ticket against whoever.
