The MOE for the sample (n=540) is +/- 4.22
Respondents were asked: Q17. If the 2012 general election for U.S. president were held today and Mitt Romney was the Republican nominee, would you vote for [randomize] Barack Obama, Mitt Romney, someone else, or haven't you thought enough about it to have an opinion?
If they initially answered that they didn't know, they were then asked a follow-up question: "If you had to make a choice, who would you choose?" Responses to the follow-up questions were folded into the results found above.
"Likely Voters" were defined as those who indicated that they were either "Extremely" or "Somewhat" interested in politics in Q2 AND either voted in "Every" or "Almost every" election in Q3.
