WASHINGTON (AP) — A Supreme Court ruling due in a few weeks could wipe out health insurance for millions of people covered by President Barack Obama's health care law. Twenty-six of the 34 states that would be most affected by the ruling have Republican governors, and 22 of the 24 GOP Senate seats up in 2016 are in those states. In the court case, opponents of the law argue that its literal wording allows the federal government to subsidize coverage only in states that set up their own health insurance markets. Praeger, a Republican who retired this year, called it "a classic death spiral," using a term for market collapse. Insurers can't turn people away because of health problems, but most healthy people are required to contribute to the insurance pool, and the government subsidizes most of the premium for low- to middle-income households. Insurers would demand relief from provisions of the law intended to limit premium increases, or they might drop out of the insurance exchanges. Many people still buy individual health care policies directly from an insurance company, bypassing the law's markets and paying the full cost. The health law created one big insurance pool in each state, combining customers who purchase their policies directly with those who buy through the government market. If the subsidies are overturned, Republicans will first try blaming Obama and the Democrats for writing flawed legislation and then trying to paper over problems with regulations. "The president is likely to veto whatever we would propose, because we don't have a willing partner," said Sen.
