If Romney is not up here currently, he is not winning it without winning the PV. It all comes down to Ohio.
We could see an expanding base for Romney as well.
In terms of states? What other states besides Wisconsin are you looking at? Obviously states like VA, IA, CO and FL on their own aren't going to cut it for Romney, though they are prerequisites. Adding NH to that list doesn't work. NV and WI are the only ones who work and I do think Romney has a better chance in WI than NV. This poll shows that WI is not a Romney state even when he is in a strong position, thus I think OH is still the key. And although I do think Opebo is trolling with his "racist whites" meme, in OH it might actually affect the race. The type of people Obama needs to win in OH tend to not like Blacks.
