I can imagine Akin going independent after kicking McCaskills arse.
You forget Moderate Republican Rule 124: "If a Conservative is winning, find an excuse not to support him so you can be buddies with your friends across the aisle"
Or "Thou salt always work against the conservatives, even if it helps the democrats."
Priebus: GOP Not Going to Play in MO with Todd Akin (No RNC Money for Akin)
He should have dropped out, there were several other candidates that conservatives would have rightfully supported in his place. This is not simply a GOPe viewpoint, it's the view of Michelle Malkin, Mark Levin and a lot of other genuine hard core conservatives.
Since he stayed in, he will have to figure out how to win with less money. At this point I hope he can do it, but his obstinant decision to stay in light of what he brought on him self is a conundrum not easily solved. Claiming it's the fault of the GOPe is far from the truth (and yes, I despise Rove too).
