Maryland Del. Dereck E. Davis (D-Prince George’s) said Tuesday that he is dropping out of the 4th Congressional District race, leaving six candidates vying for the Democratic Party nomination to succeed U.S. Rep. Donna F. Edwards (D-Md.).

Davis’s campaign manager, Jessica Semachko, said the delegate wants to focus on his legislative job in Annapolis as chair of the influential state House Economic Matters Committee, where he is expected to head campaigns on major progressive issues.

“There are very serious issues facing Maryland’s working families and small business. I fear a broken Congress will be unable to address those issues, and my first priority has always been to ensure that Marylanders have the support and opportunity to prosper and thrive,” said Davis in a statement. “. . . while this campaign comes to and end, my commitment to fighting for the future of our families and neighbors is renewed.”

The longtime state lawmaker vowed last year that he would lead the fight for paid sick-leave legislation, after similar legislation failed at the local level in Prince George’s County.

“He’s first and foremost a legislator,” Semachko said.

Davis was solidly in third place with his fundraising and came off a strong fourth quarter, raising more than $150,000. He also boasted deep roots in heavy voting districts in the center of Prince George’s, which comprises about half of the congressional district.

The lawmaker’s departure less than 90 days before the April primary leaves the Democratic contest to former Prince George’s state’s attorney Glenn F. Ivey, Del. Joseline Peña-Melnyk (D-Prince George’s), former Maryland lieutenant governor Anthony G. Brown, military veteran Christopher Warren, educator Alvin Thornton and political newcomer Terence Strait.
