They gave Donald Trump the White House — and now the president-elect could take billions of dollars in Obamacare aid from them. Data released Monday shows that Obamacare customers who live in many of the states that voted for Trump have the most to lose if the Affordable Care Act and its related subsidies are repealed during his administration.

The Kaiser Family Foundation said that as of March 31, nearly 9.4 million people in the United States were due to receive about $32.8 billion in annual tax credits to help reduce their monthly health insurance premium payments for plans purchased through Obamacare marketplaces. Half of that dollar amount went to residents of just five states: Florida, California, Texas, North Carolina and Georgia. And four of those five states — the exception being California — are set to give their Electoral College votes to President-elect Trump, who has promised to dismantle the insurance system. Of the top 20 states in terms of the value of their total Obamacare subsidies, all but five will give their Electoral College votes for Trump. "These are some states where a lot of people have opposed the ACA, but it's also where a lot of money is at stake if the ACA is repealed," said Cynthia Cox, associate director of the program for study of health reform, costs, private insurance at the Kaiser Family Foundation.
