Also, while Romney was wasting time in that stupid Republican primary arguing with idiots like Michelle Bachman, the incumbent is able to build up their ground game and get out the vote campaign. Not having to fight through a nomination process gives you an advantage as well to get a better turn out.

I don't have any proof of this and I'm not spinning it for Obama, but just watching elections over the years, that's how it always seems to play out. Being the incumbent gives you a built in 1 or 2 % bump on election day. So the challenger needs at least more than that lead to win
