I don't think she meant it that way. At least I did not take it that way. Sounds like she just is not happy in the position she is in. And why should she be. She could be leading a much better life than the campaign trail.
I take it as frustation over that more than any dislike for American. As in, do all the men in America want to be politicians. Why did I move here?
Personally, I don't think she has anything to worry about. I don't see Kerry having a chance to be president.
