The Affordable Care Act remains popular in red-state Tennessee.

The government-subsidized health insurance program saw a whopping 59% increase in enrollments in this state as of Jan. 17, the fifth-highest increase in the nation, according to an analysis by the non-profit health policy group, KFF. A record 555,103 Tennesseans are now enrolled in plans, according to government figures.

Last year, that number was 348,097.

“We had a really busy year,” said Leah Jaynes, a federally certified health care navigator in Tennessee. “We had people working very hard to get clients completely enrolled and happy with their plans.”
