Some 3 million more Americans voted for the Democratic candidate in 2016 than for Trump. In the 2018 election, Democratic senatorial candidates received 40 million votes in total while Republican senatorial candidates received 31 million votes in total. Even a majority of the American population is governed by Democratic governors.

If you actually look at votes casts by citizens of the United States, the Republican Party has been a minority party for years. The only reason why Republicans have power is that our system gives a hugely disproportionate amount power to rural areas. Example, Wyoming gets 2 senators, California, with 77 times the population, gets 2 senators. A Democratic governor of a state with 20 million people is governing more people than 5 Republican governors are of states with 2 million people in each.
However, you are only fooling yourself if you don't accept the fact that our nation's rapidly changing demographics will end up being the deathknell to the Republican Party if they continue down the road of courting racists and bigots in the parties base, rather than being a party whose base actually looks like America. The Republican Party's base is just 3% black. The country is not just 3% black. Only 14% of Hispanics identify as Republican. Only a small minority of Asians identify as Republican. The Republican Party is old, white, rural and largely evangelical - all demographic groups that are declining. That is not a winning formula for the future.
