Which of the following VP choices would be best for Obama? McCain? - Hillary/Romney out?

Personally I like Brian Schwietzer for the Democrats. I think he has vision and would appeal to me as a white working cl person, but McCaskill would probably help keep many of the Hillary voters in the Democratic fold. I am a Hillary supporter who will vote for McCain this time around. I like Romney for the reasons you mentioned. I am an economic conservative and am moderate on social issues and he would probably help turn Ohio back to red and perhaps even bring Michigan into the GOP column. He also had a lot of success out west.
