Lol. They can announce whatever they want. Debt ceiling comes Dec 8th and no CR will save them. The problem isn't appropriation, government can coast on CRs for years without a proper budget. The problem is that debt ceiling that will void whatever appropriation made over the limit.

So unless US treasury is willing to just print a whole lot of money and spike the inflation I don't see them going on without a shutdown. Best they can do is pretend they can and really go hard with the extraordinary measures, which will move hard breach to January rather than March.
