It's actually funnier/worse than that.

The Biden administration can't seat judicial picks without Feinstein because in their infinite wisdom democratic leadership chose a geriatric 86 year old to be on probably one of the most important committees in congress because she was still in "better" condition (it was already known that she'd complained of forgetfulness at the time she was selected to be on the committee).

Republicans have said they will absolutely not seat/allow a replacement (via filibuster) and the dems won't/can't end the filibuster so they're stuck with this weekend at Bernie's situation if they want any more judicial appointments this term.

For anyone who has to deal with smug annoying liberals in any capacity- this is a great way to dunk on their leadership and call out how inept they are at really basic risk management. I've found it really gets under their skin when you continue to press how terrible they are at really obvious components of their jobs.
