I am pretty skeptical that with the same type of voters in one state Romney is +30 and in OH he is magically “even” with Obama. I don’t believe that the most important issue to working class voters in OH would be the auto bailout which _has already occurred_ enough to swing things 30 points. I think this is the perils of cross tabs.
I thought the entire argument for why Romney might win the popular vote but lose the EV is something to do with Romney doing so well with white voters. I do think there is some truth that Romney performs better with affluent suburban voters than most Republicans, so it is possible he will perform like Bush, Sr. did in ‘88. That would make PA a promising state, even if OH was a bit more challenging.
Parts of Ohio are characterized as unionized whereas I don’t think that is true for Virginia except maybe northern Virginia which may have large numbers of unionized government workers.
