Everyone speaks of Libya and binders...
...but, for me, there were really three (and maybe four) other major turning points in the debate for our side:
1) Early on, Obama calling out Romney on untruths, then describing Romney's "five-point" jobs plan as a "one-point plan."
2) When Romney had the lack-of-sense to blame Obama for higher gas prices than when he took office, it set Obama up for a devastating riposte that the reason for low oil prices was the collapse of the American economy, and that Romney might indeed be able to bring oil prices back down, because he might lead the U.S. back into a similar recession.
3) Obama's rebuttal to the "how do you differ from George W. Bush?" question, which managed to make Dubya seem moderate compared to Mittens, but asserting that they shared the same disastrous economic plan.
(The possible fourth, or course, was Mittens deciding to use his final answer to assert he cared about 100% of the people, which was really a glaring unforced error, because it not only allowed Obama to bring up the 47% comment, but to do so when Mitt would have no opportunity to reply -- an incredibly dumb move.)
