Years down the road, maybe some judge will rule ICE’s actions violated voters’ Constitutional rights, but who cares? The standard punishment for that is a stern “don’t do it again”. If someone is convicted because of a rights violation, their conviction might be overturned, but that’s not what would happen here: it would just be intimidation and harassment to move vote totals and no conviction to be reversed.
It's a road map to where we end up with a similar document but a different culture.
This isn't a crazy or impossible proposition, it can be done with just a law. We already form some courts in a similar way, so it's also not unprecedented. It even avoids the naked partisanship of a simple court-packing.
As far as I can tell, nobody who matters is talking about it yet. So. Hope is... remote.
