As the end of Gov. Martin O’Malley’s tenure in Annapolis approaches, one of his aides is about to launch his own bid to become an elected official.

David Sloan (D), a special adviser in O’Malley’s office of intergovernmental affairs, plans to announce Wednesday that he is running next year for a seat in the Maryland House of Delegates representing part of Prince George’s County.

“Many of you already know me,” Sloan, 31, writes in an e-mail that is set to go out to potential supporters in District 26. He promises his priorities will include education, economic development, health care and public safety. The e-mail advertises a community rally to kick off his campaign next month.

Sloan, whose behind-the-scenes political career has also included stints as executive director of the Maryland Democratic Party and in O’Malley’s communications office, won’t be the only person on an upcoming ballot to list a job with O’Malley (D) on his résumé: Nick Stewart (D), a former speechwriter, has filed to run for the House of Delegates next year in a Baltimore-area district, and Teddy Davis (D), a former strategic communications director, is running for a seat on the Los Angeles City Council in 2015.
