As the 115th U.S. Congress deliberates the future of the Affordable Care Act, an interactive map from the Kaiser Family Foundation provides estimates of the number of people in each congressional district who enrolled in a 2016 ACA marketplace health plan and the political party of each district's representative as of January.
The analysis also includes maps charting the total number of people enrolled under the ACA Medicaid expansion in 2015 in states that implemented the ACA Medicaid expansion, along with the political parties of their governors and U.S. senators. As of January 2017, among states that adopted the Medicaid expansion, 16 have Republican governors, 14 have Democratic governors, and one has an Independent governor. In Washington, D.C., which also expanded Medicaid, the mayor is a Democrat.
