The problem (meaning one of many, many problems) with Democrats is they mass deliberate on every issue. They might put this up for discussion for a month before they kill it because of some technocratic snag the top dogs of the party get hooked on. If I recall correctly, they've already done this.
Which means we're actually already a few steps down the road in this process.
This isn't that hard. At the moment the Democratic Party has a single leader. If he endorses court expansion that's the Democratic position, at least for a while.
If you mean Biden. he's not going to. He doesn't have the stomach or nerves for it. He is neither a radical nor a visionary. He's a conservative "bipartisan" technocrat by deep nature. (If he does this, it's because someone else has taken the reins from him.)
