Delaware holds congressional primaries

Delaware held its statewide primary election on September 15. Races for two congressional seats were on the ballot—one for a U.S. Senate seat and one for Delaware’s at-large U.S. House seat. Both incumbents filed for re-election and won their respective primaries, advancing to the general election on November 3.

In the race for Delaware’s Class II Senate seat, incumbent Chris Coons (D) advanced from the Democratic primary over challenger Jessica Scarane with 73% of the vote, according to unofficial results. Republican Lauren Witzke won the Republican primary, beating James DeMartino with 57% of the vote.

Incumbent Lisa Blunt Rochester was unopposed in the Democratic primary for Delaware’s at-large U.S. House seat. The primary was canceled and Rochester advanced automatically to the general election. In the Republican primary, Lee Murphy secured 74% of the vote to advance to the general over Matthew Morris.

Delaware’s primary was the 49th to take place in the 2020 election cycle. The next and last congressional primary is on November 3 in Louisiana.
