At this point, due to the machinations of the other two branches, SCOTUS has no credibility. It is perceived, rightly or wrongly, as a political court.

So they lost that fight, and really are not empowered to reform themselves.

So the US has a political court, a captive congress, and a President from the corporate right wing of what 40 years ago ceased to be an opposition party.

It is hardly surprising that the US is only considered a 'partial democracy', or a 'failing democracy'.
