National Journal: “According to the Centers for Medicare and Medicaid Services, voter registration must be offered on the ACA exchange application because of the Medicaid eligibility determination. To be in compliance, CMS says they are including language on the paper and online applications that says, “If you want to register to vote, you can complete a voter registration form at usa.gov.” States that have opted to create their own exchanges are able to develop their own applications and choose how they enforce the National Voter Registration Act requirement.”
