Is if recent (from during the campaign) audio/video emerged of him saying that his new Pro-Life position is a fraud and just for politics. Because there's a huge chunk of the partisan Republican base that is either voting for him just on the basis of that, or would refuse to support a pro-choice candidate.
People have talked about how calling Obama the N-word would kill him, but honestly I think the overwhelming majority of that 40 percent of people sticking with him wouldn't care. This could give him the 45 state landslide loss he deserves. I know a lot of people wondering what the comment that's supposedly worse than the "grab her by the pussy" remark is and are speculating that it's a racial slur, but it could maybe be something like this that would alienate the social conservatives.
Well obviously, but he wouldn't say something like that because he doesn't really care enough to talk about it in-depth in the first place.
