In 1862, the GOP was advocating preserving the Union. In 2023, the GOP is advocating dissolution of the Union.
The GOP is no longer the party of Abraham Lincoln, Teddy Roosevelt, Barry Goldwater, and Ronald Reagan.
The GOP is being torn apart among a few rich, loud, overly-influential Globalist, Social Conservative, Seditionist, Successionist, and pro-Putin interests.
The GOP is continuing the dissolution of the Reagan coalition that started with Bush 41, greatly accelerated by Bush 43, and expertly exloited by Trump 45.
It will become increasingly difficult for the GOP to win state-wide elections. They'll win House Rep and State legislative elections, but not as many US Senate and US Presidential elections.
