An image of text is an excerpt from Cynthia Cox's quick take which reads, "While the Trump administration attributes this drop in enrollment to their attempts to address fraud, this coverage loss happened at the same time millions of people faced steep increases in their premium payments — often in the double or even triple digits — with the expiration of enhanced tax credits."

  • The Affordable Care Act and Insurance Coverage in Rural Areas

    Issue Brief
