Obama won a very big victory.
Not going to get my hopes up for a major change in the polls though.
That's the thing. I think Romney's win in the first debate was the most influential, so in terms of the debates in general, though Obama slam dunked the final two, Romney's performance did him best. What's important for the Obama campaign is that his good performance in the last two debates slowed Romney's momentum. Obama won more battles, but in terms of voter influence, it seems Romney won the war in terms of the debates.
