With the country at very near 50/50 it is not reasonable to expect much more than slim margins in the House and senate and the status quo more or less continuing.
The result is that change is not legislatively possible outside fiscal matters. The result is presidential executive orders that are modified or rescinded by the courts.
Fortunately, President Trump provided lots of judges and a conservative supreme court.
The legislative branch is not presently in the agenda business
There were a LOT of unforced errors in this election, If the GOP winds ups winning both houses it will almost certainly be in spite of themsleves...
If all they can squeak out is 1 Senate sate and a slim majority in the house in the current environment then they need to fully rethink everything.. because if that’s the best they can do in this environment, long term they have little future.
