Voters may have replaced one Democratic insurance commissioner today and re-elected another.
They also voted on three open commissioner races, and they considered the idea of setting up a single-payer health care system in Colorado.
The two incumbent commissioners who were on the ballot are Wayne Goodwin of North Carolina and Mike Kreidler of Washington state.
Donald Trump was elected the president of the United States. Trump has repeatedly promised to replace the Affordable Care Act. State insurance commissioners could play a major role in shaping any health care system changes.
State insurance commissioners will also play a major role in responding to the effects of low interest rates on issuers of life insurance, annuities, long-term care insurance and other products that depend heavily on returns on investments in bonds and other fixed-income investments.
Goodwin, a Democrat who was elected North Carolina's insurance commissioner in 2008, and re-elected in 2012, lost to Mike Causey, a Republican.
Goodwin had 46 percent of the vote, and Causey had 54 percent.
Mike Kreidler, a Democrat who's been Washington state's commissioner since 2000, won 60.1 percent to 39.8 percent over his Republican opponent, Richard Schrock.
Three states had insurance commissioner races with no incumbent on the ballot.
In Delaware, Trinidad Navarro, a Democrat, defeated Jeffrey Cragg, a Republican, by a margin of 59 percent to 41 percent.
Navarro is a county sheriff who spent a few years as a life and health insurance agent before he went into law enforcement.
