The fact that Biden called for a “commission” shows he is trying to evade the issue.
I think the “commission” idea, will be used to give “political cover” to Democrats in Congress to pass the legislation needed to make changes.
They will say, “hey, we’re just following the recommendations of experts on this non-partisan commission” to reform the federal judiciary. They will claim it’s not a “Democrat” issue but a non-partisan, “reform” or “streamline” effort to make the federal courts work more efficiently.
