“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. The map… shows estimates of ACA Marketplace enrollment as of March 2016 by congressional district, with red and blue districts representing those with a Republican or Democratic congressional representative.  Districts with darker shading have a greater number of Marketplace enrollees.  Of the 11.5 million Marketplace enrollees nationally, 6.3 million live in Republican districts and 5.2 million live in Democratic districts. Marketplace enrollees per Republican district range from 10,200 enrollees in West Virginia’s District 3 to 96,300 enrollees in Florida’s District 27, with a median of 24,300 enrollees per district. Marketplace enrollees per Democratic district range from 5,200 enrollees in Hawaii’s District 1 to 94,100 enrollees in Florida’s District 10, with a median of 23,600 enrollees per district. The ten congressional districts with the highest number of Marketplace enrollees are all in Florida. There are 17 congressional districts (8 Republican districts and 9 Democratic districts) with over 50,000 enrollees, located in the following states: Florida, North Carolina, Georgia, and Montana.”
