ATLANTA (AP) — More than 412,000 Georgians can receive tax subsidies designed to make health insurance affordable after the U.S. Supreme Court upheld the nationwide assistance on Thursday.

Experts say the court's ruling means little will change for people using the federal exchange to buy insurance.

Challengers of the Affordable Care Act argued that only people enrolled in a state-run exchange should be eligible for the subsidies.

Georgia Gov. Nathan Deal decided not to set up an exchange in Georgia, and more than 452,000 people enrolled using the federal exchange.

Deal has said that a state exchange would become too expensive. A spokesman for the governor wasn't immediately available Thursday morning.

Republican U.S. Sens. Johnny Isakson and David Perdue called for a repeal of the health care law in statements following the ruling.
