Rich, it's interesting though, lots of McCain supporters like McCain's bipartisan history, but if Obama agrees with him on some foreign policy issues, that's a knock on Barack? I find the logic kind of twisted. Would McCain supporters prefer it if Obama's views on foreign policy were more different from McCain's? I saw it as Obama acknowledging common ground, which is what McCain is supposed to be so famous for doing. Maybe that's not how it will play out on tv, though.
These debates just tend to reinforce supporter's views, though - if you're looking for a reason to back your candidate and oppose the other guy, you can always find it. What will probably decide the election is how a few carefully chosen sound bites will sound to the 10% or so of people in just a few states who a) will vote and b) have been paying no attention whatsoever to these guy's policies, history, and temperament.
The VP debate could get interesting, though - Palin seems to not understand the first thing about economics, government, or her running mate's own policies, based on the 2 (!) interviews she's given in the last month. Conservatives should really check out her Couric interview.
