All it takes and more! Anyway, not long ago, McCain had stated that he would never run for vice-president as that is a pointless job. The Vice-President plays no political role whatsoever and was invented to attract some votes. Just as an example, the term "gerrymandering" was coined after the name of a democratic vice-president and that's one of the "greatest" achievements of a vice-president that I even know of. McCain acted accordingly. He appointed a woman to get some of Hillary's votes. Got no clue whether that was smart or not but at least he had a firm position on the issue from the beginning. As to Joe Biden, I do think he is an excellent politician with a lot of influence in the NATO and very very well known in Europe. However, we all know what he thinks of Obama. The same that every politician in Europe probably thinks of him. I don't want to repeat myself though.
