The disappearing ACA insurance market

In 2017 high-profile insurance exits left 21 percent of all ACA customers with only one insurer in their area. This doesn’t even count 2018 when there could be as many as 47 U.S. counties with no insurer at all.
n other words, many states/counties ALREADY have a #SinglePayer health care system.
to all of you thinking the republicans ruined it watch the shrinking insurers under Obama. The Democrats did nothing then or now.
