Many of the big insurers have pulled out of the state exchanges as they are losing enough money it would force them out of business. That is not partisan, it is what they were telling the Obama WH even while they were in favor of ACA.  So the ACA subsidized residents have 100% of zero for every company that pulled out.  (21 % only have one company to 'pick' from -http://dailycaller.com/2017/06/19/this-map-shows-how-many-insurers-are-pulling-out-of-obamacare/ ) 

People paying their premiums cannot last 20 more years. Better to restructure now. If it is a CBO projection, I urge caution there. They have been dramatically wrong every year of ACA to present, at a huge financial blow to taxpayers.

For the 6.5 percent of the U.S. population that is in 'Deep Poverty'- of course assist them with Medicaid. (Source: https://www.ers.usda.gov/topics/rural-economy-population/rural-poverty-well-being/poverty-overview/ ) 

Child poverty is correctly addressed via CHIP, before ACA. It won't change
