If it comes down to a BC than Daniels is the best choice of the handful of names I’ve heard floating around. As for the establishment I think they realize Romney is a no sale. I wouldn’t put it past them to pump up Santorum and even Paul to create enough division needed to bring about a BC.
They also know substitutiing a liberal pub with another liberal pub isn’t going to fly with the majority.
I should have said Daniels is the least objectionable of the names I have heard being floated around.
