It's true, if the ACA is "repealed and replaced" - and that's still up in the air, I think - neither I nor anyone in the media nor anyone I have spoken to has a clue about what would replace it. I have read several columnists who say the repeal would be harder than most people seem to think. And indeed, if repealed entirely but not replaced with something at least as good, up to twenty million insured would immediately lose their health coverage. People are worried, especially those with ACA plans who have expensive pre-existing conditions. A lot of blacks and Muslims worry about a new wave of persecution. And there is much more that's up in the air. Millions of women marching against Trump do so because of the general disrespect he showed them. The Mexican peso is tanking because of worry about Trump yanking a lot of jobs out of Mexico, and charging Mexico for a 60 billion dollar wall, while returning 11 million unemployed Mexicans. People worry with good cause.
