Here a description of the ACA from Vox, a pro-Obama, progressive, pro-Democrat website:
Healthcare.gov is on track to offer shoppers fewer options than ever before in 2017.It's amusing to listen to Hillary Clinton discuss Obamacare. She thinks it's still viable and wants to "fix it," rather than replace it with something that works. That seems to be the Democrat credo over the past eight years—double down on failure.
Major insurers like Aetna and UnitedHealth have, in recent months, taken major steps to sharply reduce participation in Obamacare's insurance marketplaces. The result, a new Vox analysis shows, is a spike in counties served by just one health insurer — and a precipitous drop in ultra-competitive areas.
There are currently 687 counties on the Healthcare.gov marketplace with just one insurer signed up to sell in 2017 — nearly four times the 182 counties that had one insurer this year.
Competitive markets, meanwhile, seem to be disappearing. In 2016, 66.8 percent of Healthcare.gov counties had three or more insurers. In 2017, only 44.3 percent of counties are on track to have this level of competition.
