Todd Akin’s campaign continues to undergo one of the fastest implosions on record. Not only is Mitt Romney pushing him toward the door, the National Republican Senatorial Committee said it will yank financial support for his Senate bid, CNN reports:

The National Republican Senatorial Committee will no longer support Rep. Todd Akin of Missouri in his U.S. Senate bid, a source from the group told CNN Senior Congressional Correspondent Dana Bash on Monday.

It was communicated to the congressman that the NRSC will be pulling out if he decides to stay in the race, the source said one day after the Senate candidate sparked a firestorm by claiming that “legitimate rape” rarely resulted in pregnancy.

Akin sounded defiant on the Mike Huckabee show earlier today, saying that he had no plans to step aside. At this point, it doesn’t look like that’s possible anymore. Republican senators are calling on him to drop out, and without NRSC funding, Akin has no chance of fighting off the attacks Democrats will rightfully hit him with. GOP advisors say he’s already making preparations to exit the race, according to Richard Grenell.

What would be the point of staying in the race at this point, unless he’s actively seeking to damage the Republican Party? Akin has basically no chance of winning, few defenders in the conservative media, and zero support from his national committee. In that climate, bowing out and preventing further embarrassment for himself should seem pretty appealing.
