20 Ohio Counties likely to be without any insurance plans next year on the Obamacare marketplaces

As we have previously posted, many counties in TennesseeMissouri, and other states will have significant portions of their state without insurers in the Obamacare system.  Now a similar announcement for Ohio.  From Business Insider:
Anthem on Tuesday announced it would not participate in the individual health-insurance exchanges in Ohio for the 2018 plan year. That could leave 20 counties in the state without any plans on the marketplaces established by the Affordable Care Act, the healthcare law better known as Obamacare. 
In a statement to Business Insider, Anthem cited "continual changes in federal operations, rules, and guidance" as its primary reason for exiting the marketplaces. . . .
