Aside: You Fringers who boldly claimed that Palin would fly in, do one quick appearance with McCain, then go her own way - what happened with that?
It is glaringly obvious that Palin is doing more than just discharging her 'debt' to McCain. She is outright gung-ho for this man.
Not directly. I think she's being very careful not to do that. However, it will be interpreted in this way:
"I don't think most endorsements have much effect at all. But I think Palin in this specific race could make a difference," political analyst Tucker Carlson told Fox News, calling Palin the "de facto leader of the Tea Party Movement."
"She's the one person that the kind of voters who don't like McCain in Arizona might listen to," Carlson said. " She's the one person who might be able to convince them to support John McCain." From here.
