Del. Jon S. Cardin (D-Baltimore County) announced Tuesday that he has launched an exploratory committee to consider running for attorney general in 2014, a move that confirms his much-rumored interest in the job.

“I am exploring a run for this office to bring fairness and protection to Maryland’s consumers, students, environment, and economy and to keep it as the best state to live, work and recreate,” Cardin, a House member for the past decade, said in a statement.

Cardin, who chairs a House subcommittee on election law, is among several Democrats who have been jockeying to succeed Attorney General Douglas F. Gansler (D), who is gearing up to run for governor in 2014 in a competitive primary field.

Sen. Brian E. Frosh (D-Montgomery) has been the most visible of the would-be successors. He announced an exploratory bid for attorney general last month, releasing a list of more than 100 supporters, many of them prominent names in the state’s Democratic establishment.

Other Democrats who’ve expressed interest in the job include Del. C. William Frick (D-Montgomery) and Del. Aisha N. Braveboy (D-Prince George’s).
