People in Columbia, S.C., had their pick of four health insurers last year when they shopped for policies during the Affordable Care Act's open enrollment.
This time they have just one: Blue Cross Blue Shield of South Carolina, which had the most Obamacare enrollees in Richland County in 2016 due to its low prices.
It's a change that's been repeated around the country after big health insurers such as Aetna, Humana and United Healthcare pulled out of dozens of Obamacare marketplaces that they judged unprofitable.
