- Can Defeat Obama: Romney won voters who said the most important quality in a candidate was the ability to beat President Barack Obama (43 percent).

- Economy: The economy was the top issue for Oklahoma voters, with 48 percent saying it was the most important issue. (The next-highest issue was the budget deficit, which 32 percent of voters cited.) Romney won voters who cited the economy, while Santorum won budget deficit and abortion voters.

- Religion Not Important: As in other states, Romney again won voters who said a candidate's religion is not important. Thirty-one percent of voters who said religious beliefs mattered "not much" or "not at all" went to Romney. Those who said they mattered a "great deal" or "somewhat' went to Santorum.
