Early voting favored Monique Barial over longtime family law attorney Janet Ahern in the runoff for a vacant seat on the Orleans Parish Civil District Court bench dedicated to domestic law matters.

Barial, who until her run for the office served as minute clerk for Civil District Judge Chris Bruno, held 53 percent of the vote with less than 18,000 early votes counted, and no precincts yet in.

The runoff is for a Division H seat with no incumbent, left vacant after Judge Michael Begneris stepped down from the bench to run a failed campaign to unseat Mayor Mitch Landrieu.

The seat is being permanently converted into a domestic section, where matters such as divorce, custody and child support are handled.

Ahern, 53, who took 34 percent of the primary vote to 39 percent for Barial, has stressed her more than two decades practicing family law. Her campaign won the support of Landrieu, City Councilmembers Stacy Head, Susan Guidry and Jason Williams, along with District Attorney Leon Cannizzaro and U.S. Rep. Cedric Richmond.

Barial, 43, is running her first campaign for public office, and she has underscored her work under Bruno, who handled the domestic docket during his first three years at the court. Barial also has represented plaintiffs and defendants as an attorney in family court. Her endorsement roster includes Orleans Parish Sheriff Marlin Gusman, City Councilman Jarred Brossett, Clerk of Criminal Court Arthur Morrell and others.

Unlike Ahern, who announced her intention to run for the judgeship in 2012, Barial didn’t begin campaigning until early August because she was an employee of the court.

Ahern began her career as a prosecutor and ran unsuccessfully for a Civil District Court judgeship in 2001. She also served as executive director of CourtWatch NOLA, a watchdog group that monitors activity in the criminal court.

Ahern had spent more than $120,000 from her campaign as of the last reporting period, in mid-November, more than twice as much as Barial.
