A Republican High Water Mark?

The President is a Republican. The Republicans hold (thin) majorities in both the U.S. House and the U.S. Senate. There is a solid conservative majority on the U.S. Supreme Court.

Two-thirds of state Governors with a party affiliation are Republicans.

[T]here are 33 Republicans, 16 Democrats, and 1 independent (Alaska) holding the office of governor. Additionally, there are 2 Republicans (Guam and Northern Mariana Islands), 1 Democrat (American Samoa) and 1 independent (U.S. Virgin Islands) holding offices in the U.S. territories; furthermore Ricky Rosselló (Puerto Rico) is registered with the New Progressive Party but nationally affiliated as a Democrat. The Mayor of the District of Columbia, Muriel Bowser, is a Democrat.

Republicans also have a solid hold on state legislatures relative to Democrats:

Republicans hold 1,000 more state legislative seats than Democrats, giving them control of two-thirds of state legislative chambers across the country. This election could shift the balance in some key states: 

Democrats are within five seats of reclaiming control of state Senates in Arizona, Colorado, Florida, Maine, New Hampshire, New York and Wisconsin. 

The party is only a handful of seats away from winning control of lower chambers in Michigan and New Hampshire, too.

This is really pretty stunning from the perspective of someone who sees the Republican elite as awash with criminals, frauds, and crazies with no seriously sensible policy agenda, and a serious deficit in self-identified Republicans including big deficits among women, young people, and almost every non-white and non-Christian demographic.
