Republican governors are the party future leadership

With all this "talent" why did mccain pick palin as VP nominee

He didn't.

So it was more or less forced upon him,he knew she wasn't to bright?

He knew Palin for less than 48 hours before the decision was made. If I were to make such a heavy decision, one which I believe is what broke his bid for the hot seat, I'd have to know a LOT about the person... she didn't even get vetted!
