Oklahoma City Mayor Mick Cornett will have at least one opponent in March’s mayoral election. Joe Sarge Nelson recently announced he will try for a third time to become Oklahoma City’s mayor. Nelson, 71, was disqualified from the ballot in 2002 when he tried to run against then-Mayor Kirk Humphreys. Humprheys challenged Nelson’s candidacy, and the Oklahoma County Election Board disqualified him after ruling some of the 25 signatures he submitted with his filing were not registered Oklahoma City voters. Nelson, who runs his own construction business, made it onto the ballot in 2006 against Cornett and Bob Waldrop but finished third as Cornett cruised to re-election with a record-setting 87.6 percent of the vote. Nelson also ran unsuccessfully for Oklahoma County commissioner in 2002. Despite never running a successful campaign, Nelson said he was compelled to run when he was approached by many voters who said they were upset following the MAPS 3 vote Dec. 8. Nelson said he didn’t like the MAPS 3 proposal, which won approval with 54 percent of the vote. Cornett said last summer he would seek re-election as mayor. Filing for the mayor’s election will be Jan. 27-29. Voters will go to the polls March 2 to vote on the mayor’s race.
