Before the 2016 election, the Republican partisans insisted that fraud and malfeasance were likely, and the Democratic ones said it was impossible.
From 2016-2020, the Democratic partisans insisted that there had been some sort of fraud or malfeasance, and the Republicans insisted that it was impossible.
By the end of 2020, we're back where we were in the middle of 2016, where the Republican partisans insist that fraud and malfeasance were likely, and the Democratic ones say it was impossible.
And those are the so-called 'mainstreams' of the respective parties! The situation is part Orwellian, and part real-life satire.
