No it isn’t; not when Trump is the president and he is trying to fix the mess all of his predecessors left him.
It’s not the end of the world. Of course I would prefer he had the House too, but with firm control of the Senate he’s going to choose the next Supreme Court justices.
It sure would be a shame if The Wise Latina and Ruth Buzzy Ginsburg shed these mortal coils over the next two years.
Reagan NEVER had both houses of Congress, but he never had the kind of evidence of criminality against them that Trump undoubtedly has.
The next two years are going to be VERY interesting.
