Once again, Political Science 101 eludes someone.
Yep, and if you're looking for that someone, he's in the nearest mirror.
McCain got a bounce from her when he announced her. McCain got a crash from her when moderates and independents fled the party because of her.
Instead of trying to make yourself look more foolish with excuses, you only have to look at the number of repubs that spoke out against her and have stated they don't think she is fit to lead. Unless of course those republicans are just liars. (wouldn't surprise me)
They fled, because of McCain's economic policies and his reaction to the economic crash. McCain was at the TOP of the ticket, in case you forgot, genius.
With the focus back on the economy, Obama revamped his "McCain=Bush" campaign strategy, which McCain fed with his erratic decision.
Come back, when there's a clue in that skull of yours.
