We are now seeing for first time Bidens approval dip below 50, it's at 48 percent. The D's must be careful about criticizing Trump, Biden approval is 48-37, the same as Trump before he lost the Election.
The D's are gonna spend tax payers money on an impreachment trial. Now, that the insurrection is over, a censure resolution is much better with a Impeachment that doesn't have witnesses
Biden doesn't have an approval rating since he's not president yet. His net favorability hasn't changed much since November 3rd according to the RCP average (currently 49.7 fav / 43.2 unfav):
