Maryland Del. Heather R. Mizeur (D-Montgomery) has picked up an endorsement of her 2014 bid for governor from a police group representing 1,200 officers in her home county, her campaign announced Thursday.

“Together we will change the status quo in Annapolis and get to work on sensible reforms to our criminal justice system that improve public safety and protect our officers in the line of duty,” Mizeur said as she accepted the support of the Montgomery County Fraternal Order of Police Lodge 35.

Mizeur faces two better-known and better-financed opponents in the June Democratic primary: Lt. Gov. Anthony G. Brown and Attorney General Douglas F. Gansler, a former state’s attorney from Montgomery County.

In a statement, Jim Peacock, a county detective and member of Lodge 35, said Mizeur’s selection was an indication that “Maryland has had enough politics-as-usual.”

“Heather is a breath of fresh air, and she far outshined her competition with her knowledge of the issues, passion for public service and commitment to making a difference,” Peacock said.

Mizeur has positioned herself as the most liberal candidate in the Democratic field. This week, she announced she would become the first Maryland gubernatorial candidate in 20 years to participate in the state’s public financing system.

She previously proposed legalizing marijuana, expanding subsidized pre-kindergarten and raising the minimum wage to $16.70 by 2022.

If elected, Mizeur would be Maryland’s first woman governor and the first who is openly gay.
