The polling hasn't moved, but then again it takes a few days for things like this to sink in with the public at large. The RNC and just about any prominent GOP spokesperson has disavowed Akin, because they know they have a real problem with female voters. It's both a problem of substance and image. Akin's comments resurrect those problems at exactly the wrong time. This isn't a Missouri story, it's a national story. And it ties into Paul Ryan's plan to deny abortions to women who were "illegitimately" raped.
Akin is a problem and they want him gone. They need to change the subject. The RNC, RSCC and Crossroads have all said they will cut his funding off.
But the Tea Party likes him and the bigots at Tony Perkins' House of Psycho will back him. Odds seem to favor him staying in the race.
So what happens in October when the race is close and Akin needs an infusion of cash to bury McCaskill? You think the principled defenders of women that are Karl Rove, John Cornyn and Reince Preibus will continue to starve Akin of the cash he needs?
Yeah, I didn't think so either.
UPDATE: Another good point by Booman. Akin has two unpopular positions. First, he thinks that women who are "legitimately" or "forcibly" raped don't get pregnant. That's bonkers. But it informs his second unpopular position: women who are raped should not get pregnant. That's the official GOP position in their party platform. It's a position Paul Ryan has taken repeatedly in his votes in the House. As Booman says:
In any case, the offensive and toxic part of Akin's remarks was not his false theory of natural spermicide but his position that women should be forced to bear their rapist's children. And that's the position of the Republican Party. So, what's the big deal?
