As for your last question of why Biden supporters sound like Trump, I have no idea what you are talking about
They’re calling anyone not 100% loyal to Biden as a person republicans…
Have been for a while now
Used to just be voters, but they’re saying it about NYT, Clooney, Dem politicians, literally anyone thats not 100% for Biden is no longer a Dem in their eyes.
You don’t see how that would make someone think of trumpets?
