President Barack Obama won last night’s debate on foreign policy with Republican challenger Mitt Romney.

According to a CNN poll of 448 registered voters, forty-eight percent of those surveyed said Obama had fared better in the final encounter of the campaign compared with 40 percent for Romney. Last night’s showdown at Lynn University in Boca Raton, Florida, took place amid a tightening presidential race. The final debate focused on international affairs and security, at which Obama highlighted the diplomatic achievements he has made over the past 4 years.  Romney’s performance in the candidates’ first meeting on Oct. 3 in Denver gave him a boost in national polls. However, Obama bounced back in their second debate on Oct. 16, even though many viewers surveyed afterwards gave him a less-resounding victory than Romney had claimed in their first encounter.
