Right now, electorally Obama has the advantage in how many combinations he can win the WH, but the key for Romney is that Obama has a marginal lead in Ohio by 1 point. I think it'll be a lot closer than people think. Afterall, these polls are simply estimates and Romney was deemed the underdog by much more just 3 months ago. The momentum albeit slowing, may give him the push that he needs.
I hope Romney does win though but currently they are tied at 47% in the popular vote which really doesn't mean anything other than showcasing who has a favorable approval of who.
