200 Years of Elections to the House of Representatives, Mapped

On November 6, voters will head to the polls to elect local and state leaders, and their representatives to Congress. All eyes are on the House of Representatives, which many consider more representative of the American public than the Senate, and where a large number of seats are up for grabs. According to the New York Times, Democrats need to flip a minimum of 23 Republican-held spots to retake it. And if they do, they will be in a stronger position to place checks on the rest of Donald Trump’s presidency.

Ahead of this high-stakes midterm election comes a deliciously wonky new project called “Electing the House,” put together by the University of Richmond’s Digital Scholarship Lab (DSL) and Virginia Tech’s history department, which visualizes 200 years of elections to the House.
