Biden's actually been in politics longer than McCain. But I don't think anyone could possibly make an argument that McCain is any less of a career politician, and any more of an outsider to Washington than Biden.

McCain's saying that experience is paramount. Well, if that's the case, Biden trumps McCain on experience. Palin is saying that being new and young is what counts. While Obama is about two and a half years older than Palin, McCain is about seven years older than Biden.
