D.C. Mayor Muriel Bowser and House Delegate Eleanor Holmes Norton easily won their Democratic primaries Tuesday, and several other incumbents also took their party's nominations.
Neither incumbent faced much of a challenge and since Democrats usually take the general election in the District, both should win in November.
It would be Bowser's second term. Norton, 81, has held her office since 1991.
Incumbent D.C. Council Chairman Phil Mendelson faced stiffer competition from Ed Lazere, the longtime director of the D.C. Fiscal Policy Institute, a progressive think tank, but Mendelson still took 63 percent of the vote.
Mendelson was first elected in 2012 to fill the term of Kwame Brown, then was re-elected in 2014.
In four D.C. Council races, all incumbents won: Anita Bonds (at-large), Brianne Nadeau (Ward 1), Kenyan McDuffie (Ward 5) and Charles Allen (Ward 6).
