Councilman Carl DeMaio has padded his lead among the four main candidates for mayor of San Diego, according to a poll released Monday.
DeMaio, who has led the polling since the beginning of the campaign, received support from 31 percent of those questioned by SurveyUSA for 10News, up three points from last month.
Rep. Bob Filner, D-San Diego, and Assemblyman Nathan Fletcher -- whose switch from the Republican Party to an independent gave him an initial boost -- tied for second with 21 percent. Since the last poll, Filner gained one point, and Fletcher lost five.
If no one receives more than 50 percent of the vote in the June 5 primary, the top two finishers will face off in the November general election. That makes the race for second place especially important.
The 10News canvassing of voter sentiment found District Attorney Bonnie Dumanis in fourth place, with 13 percent support.
DeMaio's support is nine points higher than in a poll conducted by U-T San Diego released last week, but he led in that survey, as well, while Filner and Fletcher were neck-and-neck for second place. Dumanis trailed in the newspaper poll, too.
The sampling error is plus or minus 4.4 percent.
