Democratic leadership has settled on a set of demands for funding DHS. It is simultaneously ambitious and insufficient in many ways. Personally, I would ban Border Patrol from being anywhere that isn't the border. That will both reduce the gun-slinging cowboy dynamic within cities but also deny DHS a LOT of their foot soldiers.
Still, what Democrats have landed on is pretty popular with the public at large. The most popular reforms are making ICE/BP wear body cameras; independent investigations of ICE shootings; requiring a judicial warrant to enter homes; allowing people to video ICE; banning racial profiling; ban ICE from entering schools and churches; focusing efforts on deporting criminals, not just anyone who looks Brown.
This is where the upside-down nature of American politics in 2026 comes into play. The requested reforms are popular. They really aren't THAT controversial - or wouldn't have been before Trump came on the scene. Yeah, you should have a warrant to enter someone's home. Yeah, we shouldn't have a masked secret police dressed in paramilitary costumes yanking people off the street.
However, there can be no distance between Republicans and Trump. You cannot defy Dear Leader. Even if Democrats are able to pass these reform bills, there's little chance Trump will actually sign them. Shutting down the government - even just part of the government - has rarely worked to extract concessions from the majority.
Of course, if and when it doesn't work, we will be told it is because Democrats are feckless and won't fight for things. Even as FEMA and TSA close and things get dicey, and Democrats will once again face the fact that closing the government hurts people, they will be expected to cave, because no one expects Republicans to care about people beyond their base. Even though the reforms are very popular, Republicans will simply double down on cruelty in the service of Trump and his hateful legions.
