They're apparently pushing them hard, spending lots of money on them. And they wouldn't be doing that if they didn't have some numbers showing they were having an effect. Romney Inc. seems relatively content not to have the issue at the forefront in the national conversation. But it's only the 10 or so swing states that matter.
I wouldn't have thought they'd drive votes. But I'm looking at the campaign's actions and what they seem to believe is working for them. The politics of race (not to mention demonstrable falsehood) is strong.
Everybody is talking about Akin. But I wonder if this is where the action -- albeit small movements in the numbers -- really is.
