ANNAPOLIS, Md. (AP) — Maryland U.S. Rep. David Trone was reelected, defeating Republican Neil Parrott in a rematch that was much closer this time because of changes in the western Maryland district’s boundaries. Trone, a Democrat, won a third term to the state’s 6th Congressional District after it was redrawn with fewer Democrats than under the state’s previous congressional map due to a successful court challenge by the GOP. Trone’s victory preserves the 7-1 advantage Maryland Democrats hold over Republicans in the state’s delegation to the U.S. House. A Maryland judge ruled this year that the state’s congressional map approved in December after the latest census was unconstitutional because of partisan gerrymandering.
