This is an expansion of something I wrote in a thread:
If Roberts really thinks that the federal insurance purchase mandate is constitutional, then he he ought to sleep well. If Roberts ruled in favor of the mandate as some kind of act of judicial statesmanship (well . . . maybe it will get repealed anyway . . . and maybe it will help reconcile some of the left-of-center to some decisions they dont like . . . and maybe liberal Justices will be less likely strike down otherwise constitutional laws they dont like and wont impose their own policy preferences if I set a good example), then he he just did a wrong to the Constitution. He would also be delusional on how the left-of-center will react. A liberal majority on the Supreme Court will be just as aggressive as it would have been if Roberts had never been born.
