This is an odd one. Even Politico admits that they don't like each other, and after the lies she's been telling about him and the Frightening Finger of Blame she's been pointing at him, some discomfort would certainly be understandable.
John McCain's family and staff have long since made their distaste for Sarah Palin clear, and her base of supporters aren't natural McCain fans.
But the running mates have remained staunchly loyal to one another, with Palin making an exception for him in her almostly solely conservative endorsements, and McCain refusing to speak ill of her.
It's a partnership that makes sense. McCain's defense insulates her from the staff charges that she's basically unready for the national stage. And McCain needs her on his right flank.
Maybe McCain needs her but since when has she cared about seeming "unready"? She brags about her outsider status and beams whenever anybody calls her "ignorant". So are her fans and they love her for it. To them, ignorance isn't a negative, it's the reason they want to vote for her: she's just as dumb as they are. That part of Smith's "analysis" is bunk.
