Voters cite global affairs, defense, Iran, and terrorism, as crucial factors that will influence their decision on election day, according to a nonpartisan poll conducted by Harvard Kennedy School’s Belfer Center for Science and International Affairs released on Friday.

Although the study confirmed that the economy tops the list of issues concerning voters, it indicated that national security is also a strong factor, ranking above taxes and only slightly below the federal deficit. The survey was conducted immediately following the first presidential debate over the span of five days from Oct. 3 to Oct. 7th, drawing on data collected from approximately 600 voters from each Ohio and Florida.

Half of the voters surveyed said they wanted the United States to pursue more active policy overseas, while the other half advocated that the United States engage in more isolationism. More than 40 percent of voters in both states said that they viewed the Arab Spring as “not good” for American interests. In particular, voters said they were concerned that ongoing conflicts could deteriorate into wars. Only a small fraction of voters expressed human rights or environmental concerns.

Although the survey determined that some American voters have a patchy knowledge of major international figures—more voters knew more about soccer player David R. J. Beckham than they did about British Prime Minister David W. D. Cameron—they showed an avid interest in foreign policy issues.

The voters surveyed said they follow foreign affairs almost as closely as they follow domestic news. They supported an increased focus on geography and foreign language in schools and wanted to see more international coverage in news sources. In future debates, voters said they hope to hear the candidates’ positions on various global security issues, including defense, Iran, and terrorism, among others.

In Ohio, the polls showed Obama with 46 percent, beating Romney, who trailed with only 38 percent. In Florida, the poll showed Romney with a slight edge of 47 percent to Obama’s 43 percent.
