Post-debate, SurveyUSA's new Ohio poll shows an even split between President Obama and Governor Romney, 45 percent to 44 percent. That's a good deal closer than the Buckeye State was in September. And yet, evangelicals are notably less than enthusiastic about the, well, Mormon candidate. 

Four years ago, they backed John McCain over Obama 71 percent to 27 percent. According to SurveyUSA, they favor Romney over Obama by just 57 percent to 37 percent. In a state where they constitute nearly a third of the voting public, that's a seven percent difference in the total vote.

Clearly, Romney has failed to seal the deal with Ohio evangelicals. As he tries to move to the center of the political spectrum in the final weeks of the campaign, he's got to convince them that he's still in their corner on the big social issues. Ergo, his effort both to allay fears that he'll lessen women's right to choose even as he seeks to convince the base that he's "the pro-life candidate."
