Gee, I don't know. Way back in the day, quite a bit got done via the courts. Desegregation and yes, bussing.  Miranda warning, 4th Amendment protections and so on. Of course as Americans have dumbed down and put more conservatives on the Supreme Court, the people have steadily lost protections. Trump's base - and a lot of more moderate Republicans - don't really realize that because they have yet to experience jack-booted police thugs invading their homes. None of them think they will ever need such protections; no, they assume the protections and rights enumerated in the Bill of Rights, for example, only protect "criminals."  If it took middle class white people losing jobs and getting kicked out of their homes to get people's attention under Bush's watch, when Trump starts going after the middle and user middle class, they'll start to wake up. Some already are. And let's not forget the International communities and trading partners. Trump is not making friends.
