I am going to re-iterate my warning about getting too excited about a Romney surge and win. Romney may very well win and win big. There could very well be a big sure for Romney on election day as independents, dissatified with Obama over the last four years break heavily for Romney. Romney already looks like he will take FL, NC, VA but Ohio is unclear and for Romney to win the election he needs Ohio and it's difficult to say where he stands there.
The polls in Ohio don't matter because they only count likely voters and this election has nothing to do with the likely voters in Ohio. It is all about the unlikely voters, ie college kids, senior citizens, homeless, etc who've never voted before. This is where ground game comes into play. The obama campaign has had an effective infrastructe to get out these unlikely voters from the '08 campaign and it is still working. They are herding college kids on the campuses and taking them to early voting on buses. That's how they will most likely take Ohio. The Romney campaign almost gave up on Ohio and there ground game is weak. This is evident when listening to Rob Portman or Ohio's Republican governor talk about the campaign.
It's still early and anything could happen like a 1000 point drop in the dow which could scare the crap out of the independents to vote Romney, but I'm not hopeful.
