The select committee only operates at the will of the current treasury head. A victory for Cain or any other Conservative (Perry, Pawlenty, etc) would mean a rejection of Obama’s agenda. To get the numbers for a Presidential win, that means you would have greater Republican turn out, and thus, it won’t just be the Presidency that is affected but house and senate races as well.
It would also be a swift kick into the general attitude of Obama’s theories. He has put all his cards down and if they are rejected, the Dems would be afraid to go back there for a while lest they also lose their jobs.
I think all of our candidates reject Obamas agenda.
