I watched the last half an hour of it, and although I'm too young to give a piss about politics it seemed as though both McCain and Obama had stereotypical answers when the Russians were brought into the debate. I'm sure if they had more time, they could of came up with better answers than "Russia did not have the right to invade Georgia/going to invade the Ukraine", which is ironic, because America too did not have the right to Invade Iraq.
Personaly I would rather Obama as president, but he didn't "flare" in this debate. McCain was more hands on in the sense he got up to shake the guys hand when he asked a question, and Obama followed suit by Thanking him for his service only - Desperate attempt to copy McCain. During the last couple questions regarding Iraq, Afghanistan, And Iran McCain had an edge over Obama because of his experience, but his policies are Bush's policies - "Invade and hope they will agree to stop whatever they were meant to stop while its too late to retreat because the country has become a haven for insurgencies".
I think Obama's idea of talking with Iran is good because as he explained under Bush's reigm; because they didnt talk with North Korea and Iran, they more than quadrupled their nuclear activities - which is frightening.
