It looks like the Trump Court will hear the suit against the ACA with a full pack of conservative justices. That means it will be overturned (even if one conservative judge defects, that's still a 5-4 loss). I have serious questions about the immediate consequences.
1. Assuming it is overturned in its entirety (as the Republicans want, rather than invalidating one clause), how soon will people be hurled off the ACA healthcare exchanges? Immediately? Or will there be a grace period, at least? Some people depend on the ACA to stay alive, on a daily basis. Will they have time to find some other coverage somewhere?
2. Assumption #1: We win the White House and the Senate. Then Democrats can pass a new version of the ACA (call it the "Awesome Care Act," or ACA2, which would be largely immune to court challenges). How long would that take? How long would people be without health care?
3. Assumption #2: We win the White House but not the Senate. Would there be anything that Biden could do in conjunction with the House? Or would everybody be screwed?
4. Assumption #3: We lose the White House, but win the Senate. Of course, Trump has no bigly health plan, and won't bother to even make a gesture of creating one. Could the Senate do anything?
5. Assumption #4: We lose the White House and the Senate. The dark times continue. Millions of people die for lack of health care. Fortunately, this nightmare scenario is pretty unlikely.
California recently announced that it will pick up the tab for Medicaid and ACA-insured patients if their health care is lost. Oregon officials have said so as well, albeit informally. That was, however, before the pandemic and the massive drop in state tax revenues, coupled with high unemployment insurance expenditures, gutted state budgets. I doubt that either state can do that now, though Oregon had a $5 billion "rainy day fund" before the pandemic hit and has only spent half of it. I don't know how much of a reserve California has, but it's a pretty wealthy state.
Another thing I think we'd all like to know is if Covid will be considered a "preexisting condition" and anyone who has recovered from it will be denied health insurance coverage. I can easily see how people might refuse to get tested for fear of testing positive and losing their health insurance when SCOTUS destroys the ACA!
