House Incumbents Most at Risk

This special edition map is designed by the Cook Political Report team to rack which incumbents (or retiring incumbents' districts) are most at risk in the redistricting process. Hover over districts to view current district partisanship (Cook PVI), the number of residents each district would need to gain or lose to reach its post-2020 Census target population, and level of vulnerability. These evaluations are subject to change as the redistricting picture in each state develops. Click on any state for our in-depth analysis, including maps of current districts and possible scenarios. 

Be sure to also check out our state-by-state redistricting outlook.
