If the Supreme Court rules for the plaintiffs in King, only people in the 16 states and the District of Columbia that set up their own Obamacare exchanges would be eligible for tax credits that would reduce the cost of their monthly health plan premiums. Those tax credits are available to people with low and moderate incomes.

In states that have not set up their own exchanges, 55 percent of respondents told the Kaiser poll that their state should create their own exchanges to protect subsidies for residents if the Supreme Court rules they cannot be given to HealthCare.gov customers.
The next day that the Supreme Court could issue a decision in the case is Thursday. Experts agree that if the subsidies are ruled illegal in HealthCare.gov states, up to 8 million people would become uninsured by next year, and premium prices for individual health plans would rise dramatically.
But advocates for the plaintiffs in the case argue that the Affordable Care Act is clear in saying that subsidies can only be given to customers of a state-created exchange, and that any extension of the subsidies beyond those markets results in an illegal burden on the taxpayers forced to pay for that assistance.
The Kaiser poll also found that public opinion overall on Obamacare remains almost evenly split. A total of 42 percent have an unfavorable view of the law, and 39 percent have a favorable view.
