Letting the government shut down is literally the only point of leverage the Dems have. This is them actually doing something for the first time in almost a year of Trump 2.0.
The alternative is just letting all the cuts the want to make in this budget go through uncontested in a complicit abdication to the fascist, patently betraying their constituency (even more than they already largely have).
We can make on hell on earth happen for them with enough support. Inshallah.
