None of these associations have any affect on Obama supporters. It’s a reflection of them. Who it will affect are the undecided/unwashed out there. Even if they’ve made up their mind at this point, information like this may well have an affect. Hopefully it will.
As for McCain, what we’re seeing is his Senate experience/seclusion from real America come out. He’s operating on Senate rules; not campaign necessity. That’s why Sarah Palin is the fresh breath of air in the equation. And that’s why, I believe, she’s the one to count on; not McCain.
