evidence: Trump Is Trying Hard To Thwart Obamacare. How's That Going? [...] Overall, Nicholas Bagley says, the ACA has been "pretty resilient to everything, so far, that the Trump administration has thrown at it." Some of Trump's efforts to hobble the law have been caught up in the courts; others have not gone into effect. And despite efforts to lure people away from the individual insurance marketplaces or to make ACA policies unaffordable, "the marketplaces have proved themselves to be remarkably resilient," Corlette says. [...] The piecemeal attacks on the ACA have made many people nervous about the future of their health coverage, Gluck says. "The most important theme of [Trump's] administration of the ACA has been to sow uncertainty into the market and destabilize the insurance pool," she says.
