Please correct me if I am wrong... but even a continuing resolution bill still needs the president’s signature. So, Trump doesn’t sign the bill without the funding and they send home a bunch of dem federal employees. That is more than show.
The signature of whoever was president then. That’s what they’ve been stacking up since the Bush 1 shutdown, more and more continuing resolutions that will just roll. That’s how they went 4 years without even debating much less approving a budget. There’s nothing for Trump to sign, Clinton, Bush 2, and Obie signed it all already. The only time we have any kind of “shutdown” now is when they start bumping into the debt ceiling, and even those average “shutting down” around 10% of the government. With nothing for him to sign nobody is getting sent home, and it is just a show.
