Of the registered, 588 were determined by SurveyUSA to be likely to vote in the 06/05/12 primary. If no one candidate receives a majority of the vote in the primary, the top two finishers will advance to a 11/06/12 general election. Incumbent Mayor Jerry Sanders is term-limited.

Respondents without a home telephone (18% of adults, 15% of likely voters) saw the questions presented visually on their smartphone or other electronic device.
