Neither Republicans nor Democrats have fully accepted the outcome of an election in this millennium. Lest we forget, in 2016 Democrats claimed that Russia threw the election for Trump. In 2008 Obama was accused by the GOP of voter fraud (Acorn, etc.) and not being an eligible US-born citizen. Democrats still seethe today about how the supreme court stole the 2000 election for Bush II by ordering the cessation of recounts in Florida. Partisans on each side believe that their own claims of election theft are proven and obviously true, while the claims of the other party are blatantly ridiculous and dishonest. In other words, the US stopped trusting and respecting the outcome of presidential elections decades ago, and everything that happened in 2020 is simply par for the course in modern times.
