C'mon. Anyone being criticized like that by both parties for several days is going to suffer a point loss. If every single Democrat came out today and called Obama a Communist who's trying to destroy America, don't you think he'd suffer some point losses?
Also, Akin was up by 9 points before this gaffe. So the rumored Democrat strategy of supposedly helping to nominate him had been failing pretty miserably for a while until a rather random event. Not buying the conspiracy theories on this one that the Democrats had this planned all along.
