US Supreme Court Justice Anthony Kennedy is retiring. That means that Trump will appoint his 2nd Supreme Court Justice and give the ultra-conservatives a majority in all three branches of the US government. Kennedy himself was conservative, but he was much more libertarian and fairly balanced by today's conservative standards.
With this appointment, Trump and his cult will have carte blanche to do whatever they feel. It will be on the Democrats and their base to show up in November or else hell will break lose.
