- Obamacare Rates Soar as White House Refuses to Make Long Term Commitment to Subsidies USA Today by Jayne O'Donnell — Insurance rates for those who buy health care coverage through the Affordable Care Act keep rising because of continued uncertainty about the Trump administration's plans for the law, officials and insurance experts say….The questions about what the administration will do about subsidies are the "main cause" of rate hikes, says Sara Collins, a vice president at the health policy foundation Commonwealth Fund. Insurers have said somewhere between 15 percent and 40 percent of their rate increases were due to administration efforts to undermine the law, according to ACASignups.net.
