In this election, Trump received more votes than any other sitting president in history. He lost and now the Democrats seem to assume that those 75M people will suddenly change their beliefs because 78M people hold different beliefs. Moreover, it seems that people voted
against Trump more than
for Biden because they thought Trump was rude and distasteful.
They fail to recall that this was actually a political route for Democrats. Democrats lost seats in the House when they were expected to gain. They eked out parity in the Senate that probably disappears in 2 years. More importantly, they lost almost all state government races.
Remember, Trump's biggest policy positions (bring our troops home, bring our jobs back, hard on china, the wall, etc) were all Democrat positions a mere 5-7 years ago. Now that the Republicans have taken over those more centrist ideas, they have gained a huge number of supporters.
The Democrats are fractured between centrists and progressives. That fracture is much worse than the Republicans because it is ideological while the Republican fracture is a cult of personality.
Trump will fade. Another person will replace him. They will have all of his populism and charm (yes, he's a natural entertainer). They won't have his rude abrasiveness. He'll then have the majority needed to censor the other side now that the Republicans have decided they agree with the progressives on that point.
