2020 Wisconsin's 7th congressional district special election
From Wikipedia, the free encyclopedia
A special election was held to fill the remainder of the term in the United States House of Representatives for Wisconsin's 7th congressional district in the 116th United States Congress. Sean Duffy, the incumbent representative, announced his resignation effective September 23, 2019, as his wife was about to give birth to a child with a heart condition.[1] Governor Tony Evers chose January 27, 2020, as the date for the special election, with the primaries scheduled for December 30, 2019.[2] However, the Department of Justice said that this schedule would be in violation of federal law, since it would provide insufficient time for overseas and military voters to receive ballots. Evers then rescheduled the primaries for February 18, 2020, and the general election for May 12, 2020.[3][4]
