In what’s been described as a dual victory for the Democratic establishment, candidates backed by party leadership won the Senate primaries in Maryland and Pennsylvania. In Pennsylvania, Katie McGinty defeated former Pennsylvania Congressmember Joe Sestak, to face Republican Senator Pat Toomey in November. Vice President Joe Biden had stumped for McGinty while the Democratic Senatorial Campaign Committee spent more than $2 million on TV ads to support her. In Maryland, Congressmember Chris Van Hollen defeated progressive Congressmember Donna Edwards for the Democratic Senate nomination. He’ll run to replace retiring Senator Barbara Mikulski in November. Edwards would have been Maryland’s first black senator and the second black woman ever to serve in the U.S. Senate. And Maryland State Senator Catherine Pugh won Baltimore’s Democratic mayoral primary, defeating 11 other candidates, including Black Lives Matter activist DeRay Mckesson.
