The Democratic field for the next attorney general of Maryland is officially growing by two.

Del. C. William Frick (D-Montgomery) filed his paperwork with the State Board of Elections on Wednesday, and Del. Aisha N. Braveboy (D-Prince George’s) said she plans to file as a 2014 candidate by the end of the day Thursday.

Frick and Braveboy — who had been acting very much like candidates already — will officially join a competitive primary to succeed Douglas F. Gansler, who is running for governor next year.

Two Democrats have previously announced bids for the attorney general post: Sen. Brian E. Frosh (D-Montgomery) and Del. Jon C. Cardin (D-Baltimore County).

Frick, a member of the House of Delegates since 2007, said he would make a formal announcement about his campaign in coming weeks.

“I am proud of my work protecting consumers as a member of the General Assembly, and I am excited to build on our progress as attorney general,” he said in a statement Thursday.

Braveboy, a House member since 2007, said she plans a kick-off event in October.

“I’m all in,” she said.

No Republicans have yet announced for attorney general.
