This is the only comment on the US election you'll find on this blog. McCain's arms are too short by a good few inches. They're just not long enough. I've watched him time and time again on the news and they're definitely shorter than they should be. Every time he raises them up to the horizontal I say to meself "Yep, that chap's arms are too short."
So when he meets other world leaders and they reach out to shake hands, there'll be an embarrassing gap because he won't quite be able to reach the other chap's hand. And for this reason, I doubt the electors of the US will put him in the White House.
