I think it's likely they want to keep Trump in their back pocket for later. Should he survive court. Transition from the Floyd riots to Jan 6th and there was dead silence because I assume the first person that came to their minds was Trump. (However, these things are interchangeable and it could be the Democrats next time around.) I think overall it's stand-offishy. Joe's wants to run again so there is that issue. And Trump in a hypothetical primary and I'll believe differently when I see it. There's hasn't been a reason to during the Trump era.
