Democrat John LaFerla says he is not conceding to apparent nominee Wendy Rosen in the primary election in Maryland’s 1st Congressional District. Rosen led by 126 votes out of more than 24,000 cast in last week’s election. The State Board of Elections said that votes from one precinct with 88 registered Democrats remained to be counted. The board also will start counting absentee ballots. The absentee counting process ends April 13. Rosen declared victory, but LaFerla says he will wait for the final tally. The winner faces Republican incumbent Andy Harris, who was unopposed in the primary.
