Do you really think so? I can't imagine BO would be that stupid. To be sure, I suspect that folks who agree with Ayers about education radicalization would end up running the Dept of Education. But that's different than actually trying to get congress to approve a known terrorist for a cabinet spot.
He would be putting the rats in the Senate in a terrible position. We could retake the Senate in 2010 if they approved his appointment. One could only hope he would try. But I doubt we would be that lucky.
