President Trump left little doubt yesterday that he intends to do as much damage as he can to the Affordable Care Act's insurance markets. And he can do a lot.
The bottom line: The executive order Trump signed yesterday aims to undercut some of the ACA's core ideas about how insurance markets should work. His decision to halt the law's cost-sharing subsidies will blow up those markets in the short term. And his administration has taken a slew of other steps to undermine enrollment. There's one constant here — to wound the ACA as badly as possible.
