On the foreign policy question he did well but I wish he would come out and say that his non-interventionist foreign policy is the historical conservative and Republican foreign policy. Foreign adventures abroad has historically been a liberal idea. The neocons are just liberals who became Republicans during the Cold War.
I agree. I'm not sure why he doesn't refute the assertion that supporting intervention overseas is a "right wing position." As you said, historically non intervention has been the conservative position.
