Obama fucked up there. Its not really custom for the candidates to shake hands but they do shake the hands of the wives. McCain came up and showed his wife towards Obama to shake hands ... Obama should have gone for her hand not his.

The McCains and the Obamas moved about the stage separately for a little while after their debate, greeting people on the stage, but not each other. Then John McCain tapped Barack Obama's back briefly and Obama turned and reached his hand out. Rather than shaking it, McCain directed him to his wife, Cindy.
If it wasn't clear on TV, photos showed that the two men did shake hands after Tuesday's contest.
