Presidential debate unlikely to affect election

Though polling after Monday night’s presidential debate showed President Obama as the clear winner, the debate is unlikely to make a significant difference in the election. An average of “snap polls” of debate viewers had Obama winning by some 17 percentage points (including a 30-point win in a CBS News poll). But the topic of the debate – foreign policy – is not a priority for most voters, and Mitt Romney was able to meet the basic test of the debate: appearing as a credible commander in chief.
