"Obama did not appear to suffer any damage. Fifty-four percent said the debate did not change their opinion of the president, while 16 percent said their opinion had improved and 18 percent said they viewed him more negatively.
Obama's favorability ratings remained unchanged, as 56 percent said they viewed him favorably and 44 percent said they viewed him unfavorably. His standing improved among independents by 8 percentage points.
Romney appears to have made his greatest strides among his fellow Republicans - a development that could help his fundraising and get-out-the vote efforts in the final weeks of the campaign.
Forty-six percent of Republicans said their opinion of Romney was "very favorable" after the debate, a gain of 10 percentage points."

Quick Take: Romney is still trying to lock down his base, and Obama is trying to expand the playing field.
Obama is always playing the long game, Romney chucking another last ditch Hail Mary that in retrospect, probably ends up hurting him more than helping him (http://election.princeton.edu/2012/08/15/ryan-is-a-game-changer-but-not-for-romney/)
