Although some griped Sarah Palin was never appropriately vetted as John McCain’s running mate, the lawyer in charge of choosing her said he was “very impressed” by the Alaska governor. And after a campaign of shockers, A.B. Culvahouse insists the McCain campaign knew everything about Palin when they chose her. “Everything except the pregnancy of her daughter was on a response to the written questionnaire,” Culvahouse, McCain’s attorney, said of the process. “She told me there was one issue she wanted to talk about when we went in for the interview. We knew everything going in.” And Culvahouse says Palin hit a question about why she wanted to be vice president “out of the park”...don’t tell that to Katie Couric.
