Congressional incumbents win district primaries

Early voting and Election Day counts were enough to call winners in 12 of 16 congressional races, even as hundreds of thousands of mail-in ballots have yet to be counted. The Republican contests in districts two, three, four and seven were still too close to call Wednesday. All seven incumbents representing Maryland in Congress and U.S. Senator Chris Van Hollen secured their parties’ nominations Tuesday. But come November, newly drawn congressional district maps assigned this year by the Maryland General Assembly may set up some historically blue districts to trend purple, giving the winners of Tuesday’s Republican primaries a wedge into traditionally Democratic strongholds.
