They didn’t postpone up for Trump in the four years he was in office.
Maybe they don’t see the need to big up their main man the way Trump supporters do.
Maybe they’re blind. Maybe Biden hasn’t done anything to impress them yet. Maybe he’s not been in post for long enough for them to expect any results.
I agree, they are still feeding off of the “Trump is out” we still must impeach etc. No “forward looking” from them.
