It's a pretty good reminder that:
a)Most gubernatorial elections take place during mid-terms, and
b)The party holding the presidency has a huge disadvantage during most mid-terms
Also, odd years particularly lend themselves to localization and slow walking national trends. Remember, the VA GOP still holds multiple Clinton 2016 seats in each chamber of the state legislature despite (finally, after 3 consecutive cycles of Dem presidential wins) losing the majority. I think it's fair to say that would not be the case if the legislative elections were held in 2020, and that Beshear would not even come particularly close in KY with Trump at the top of the ballot.
