I am Happy?
I'm not carried away, but I like foreign policy, and Barack Obama chose a foreign policy specialist. I had recently heard some rather surprisingly nice things about Evan Bayh, being a former Governor in Indiana, his role in Title IX and some other women's issues, and his father's role in Civil Rights. He would have been the Domestic Policy choice, and I'm "happy" that, instead, a foreign policy person was chosen.
Combined with McCain's specialization in military/overseas matters means we might have some serious foreign policy debates which, regrettably, won't get much past the establishment position.
