As Republican lawmakers work on new legislation to replace or repeal the Affordable Care Act, also known as Obamacare, there could be signs that the system may already be starting to falter.

As Republican lawmakers work on new legislation to replace or repeal the Affordable Care Act, there could be further signs indicating issues pertaining to Obamacare.
Based on an analysis conducted in conjunction with the Robert Wood Johnson Foundation, Axios has concluded that “If insurers like Anthem decide to exit the exchanges for 2018, hundreds of thousands of people would be stranded without any available insurers. Some state marketplaces would almost certainly fall apart.”
In fact, the publication speculates that if Anthem did decide to drop out in 2018, about 255,000 people across four states would have no providers under Obamacare and about 560,000 across eight states would be left with just one option. 
The analysis was prompted by the announcement that insurance company Humana would not be participating in the Obamacare marketplace next year. 
CEO Bruce Broussard told analysts last month, “...we continue to see further signs of an unbalanced risk pool. Therefore, the company has decided that it cannot continue to offer this coverage for 2018.” 
President Trump commented on the decision by tweeting, “Obamacare continues to fail. Humana to pull out in 2018. Will repeal, replace & save healthcare for ALL Americans.”
However, Axios points out that the plan Republicans are proposing is not helping to convince insurers that there will be more stability in the marketplace if it were passed. 
The Hill is reporting that the Congressional Budget Office has released its analysis of the GOP bill and estimated that the plan would likely cause 14 million Americans to lose their health coverage in 2018.
