On the negative side Trump didn’t run on limiting/reducing government like Reagan. He ran on running government “better”. Trump supporters are going to find out those aren’t the same thing.
Republicans remain in control of both houses of Congress, albeit with smaller majorities. Chuck Schumer is set to become Senate Minority Leader next year. He is going to be point-man in blocking NRA’s agenda, especially for SCOTUS replacements.
At the state level, it appears the Republicans, with some help, will maintain control of the State Senate. Incumbent Michael Venditto is behind in SD-8, but Chris Jacobs won in SD-60. The Assembly stays pretty much the same so next session will probably be a lot like this session. Fortunately, I still have some tequila left over from yesterday.
