Quick and easy access to video on the internet sure makes fact checking easier, doesn't it? In last night's debate, John McCain went after Barack Obama for being "wrong" on the surge. That one is impossible to check out, because there are many and varied opinions as to what the surge was, and to whether or not it "worked."
Obama then fired back at McCain at McCain's own history on Iraq. He quite rightly pointed out that the surge occurred in 2007, and that the invasion of Iraq started in 2003, long before the surge was even conceived. He then rattled off a list of things that McCain was wrong on. Great stuff, and this video bears him out.
