You'll want to read Jonathan Turley's article today:
No. Don't get your hopes up. Roberts isn't about to switch to being against the ACA. He's apparently about to simply contradict himself and switch his rationalizations for supporting the idea that the ACA is constitutional. If you don't feel like reading the article, here's the twitter version:
...Roberts could create a bizarre precedent: he saved the ACA in 2012 by declaring the individual mandate essential and then could save the ACA again in 2020 by declaring that it not essential. If that seems confusing, welcome to the world of Chief Justice Roberts on the ACA.
Roberts effectively acknowledged that he was a chump in accepting the arguments on the individual mandate eight years ago. For years, Roberts has been on a collision course with himself — and yesterday he had a one-person pileup.
...What is interesting is that Roberts took the bait and now appears ready to do his own switch. He suggested that he would again save the ACA through severance but do so on the basis that his earlier position is now invalid.
It's a bit difficult to imagine that his colleagues have much respect for Roberts.
