The blue states assume they are going to get to decide what happens to homeless people next, presumably for the better.
The blue states are pushing to be allowed to put homeless people in jail again. Martin v. Boise required you to have enough shelter beds/housing available before you could force homeless people to leave the street. The blue states are joining the SCOTUS case because they will not build shelters. If that doesn't indicate that they have no intention of doing better, idk what does.
They will be able reshape America how they see fit
They don't need the other two branches of government to do this. They've already got the only one that matters and are doing it now even with a Democrat in the Oval Office.
