I'll have to argue there. It's not just Democrats, both parties are massively at fault. They both fail miserably at policing their own. The Marjorie Taylor Greene nut job says all sorts of insane things, and it takes days for any republicans to rebuke her, and only then they barely do.
Both sides are doing a great job of dividing.
Okay, you have a point. But, It seems to be worse on the Democrat side.
