The Downballot's calculations of presidential election results by congressional district, sponsored by Grassroots Analytics

Our one-of-a-kind collection spans from 2008 to the present

Below are The Downballot's calculations of the presidential election results for the 2024 and 2020 elections according to the congressional district lines used in 2024.

Note: These calculations do not yet reflect the impact of redistricting undertaken since the 2024 elections.

The results for 2024 are visualized in the cartogram at the top of this post, which shows each district equally sized (click here for a traditional map).

We've also published a detailed explanation of our process for calculating the 2024 results, as well as an examination of our key findings.
