Palin did irrepairable damage to her image durring her brief stint on the national stage. That was planned though. I'm not sure if everyone noticed, but the McCain/Palin campaign was designed to take a dive. Palin was a big part of that. They got someone w/ Bush 43's fundamentalism, coupled w/ her "anti-femenist" femenism, and they knew she would elicit disdain knowing that the current political atmosphere here in the US is very anti Bush.
If she comes back in 2012 though, maybe another
morning zoo crew will prank her, and get her to admit who her overlords are.
