The selection of Sarah Palin was met with praise from the GOP, and mixture of shock and critics from the Democrats. Certainly part of the thought process was to get some Hillary voters. She is also a strong 'classic' Republican and pro (life), something many questioned on McCain.
My initial thought was that it would hurt McCain's experience argument, but from a better prospective, McCain's experience didn't go away. As far as executive experience, Palin is in better shape than Obama. So how could Obama even think about trying to raise that argument. He has had one year in the senate, and two years of campaigning.
I believe McCain is taking a chance, but my initial feelings are that it is a winning chance. I don't see it hurting, but it has MORE than potential when it comes to helping him.
We will see...
