The Senate Conservatives Fund hasn't gotten involved yet. And even if they do, how much can they commit to a single candidate out of their total war chest? By dropping Akin so publicly when his gaff first happened, the GOP party leadership has pretty much tied their hands on how much they can help.
If polls start showing the GOP losing the race to gain, at least one seat to get a majority in the Senate by mid Aug, I expect to see a turnaround in the Senate Conservatives Fund priorities. I am still optimistic that voter enthusiasm to kick McCrackel out of office as well as Akin riding in on Romney's coat tails will give him the win we need.
