My take: the DHS shutdown is not really about TSA, airports, or the rest of the department. Those are the hostages. The actual fight is ICE. Democrats have made clear they will help fund DHS if Republicans accept limits or reforms on ICE. But that proves the point: ICE is not some side issue or bargaining chip at the edge of the table. It is the table. If Republicans concede there, they are conceding the entire reason this bill blew up in the first place.
