Millions of Americans who rely on Obamacare for health insurance are staring down another double-digit price hike next year, adding to the financial toll that has already pushed millions of others to drop coverage since last year.

The increases largely reflect higher medical costs nationwide. But they also signal the latest blow to Obamacare under the Trump administration, which has overseen the expiration of tax credits that helped Americans pay for coverage and has erected new barriers to enrollment in an effort to root out what it describes as widespread fraud. Because nothing says "fraud prevention" like making it harder for sick people to buy insurance.

According to an analysis Friday by KFF, the health research group, the average price of health insurance in the Obamacare marketplaces will rise by 13 percent next year. The Trump administration on Friday published new prices for 2027 in 30 states with markets managed by the federal government. Using that data and state figures, KFF calculated the increase nationwide.

The large premium increases for Obamacare plans are similar to changes expected in other health insurance markets, though slightly higher. Reports by several consulting firms projected that premiums for employer plans, which cover around 150 million people, could go up by about 10 percent in 2027. Premiums for federal workers are increasing by more than 10 percent. So if you're keeping score: everyone's paying more, just not equally.

Public opinion polls have shown that the cost of health care has been among voters' top economic concerns going into the midterm elections on Tuesday. In a recent KFF poll, about 60 percent of registered voters said they were worried about being able to afford health care for themselves and their families. The other 40 percent are presumably worried about something else, like whether their insurance will cover the worry-induced ulcer.
