Author and former nonprofit leader Wes Moore claimed the Democratic gubernatorial nomination, calling his matchup against Republican state Del. Dan Cox “a choice between unity and division.” Moore, 43, surrounded by Democratic elected officials and allies, addressed the media in Baltimore on Saturday. The Associated Press declared him the winner on Friday night as mail-in votes were being counted. Former U.S. Labor Secretary Tom Perez, Moore’s closest rival, conceded on Saturday, saying, “Now is the time for us to unite.”
