Whether Todd Akin stays or goes comes down to how much money the grassroots of the conservative wing of the Republican Party throws his way in the next 12-24 hours. Establishment Republicans and the national party committees have yanked their support, and for a time earlier this afternoon that looked like it would be enough to shove Akin out of the Senate race. But Akin says he’s in it to win it — and, oh, send me money. The only thing propping up Akin, even in his own mind, is the notion that the grassroots can supply enough cash to sustain a campaign. But he needs more than a notion. He needs to see real results and fast. I wouldn’t rule it out. Rogue Republicans were a hallmark of the 2010 campaign. The main difference between Akin and Sharron Angle or Christine O’Donnell is that he’s a sitting member of Congress. Less rogue, perhaps, but also less easy to dismiss. How much money can he raise in the next 24 hours — and how much of it will come from self-interested Dems trying to keep him in the race?
