If Barack Obama were the Democratic Party's candidate and Mitt Romney were the Republican Party's candidate, who would you vote for Barack Obama, the Democrat or Mitt Romney, the Republican?" Those who are undecided are further asked if they lean more toward Obama or Romney and their leanings are incorporated into the results.
