This is interesting. “Schumer warns of ‘Trump shutdown,’ lays out 4-pronged plan for Democrats”
https://thehill.com/homenews/senate/5136221-schumer-trump-shutdown/The question is if this happens, who will the people blame for the shutdown? Historically, it’s been congress who gets the blame. Usually the party out of power, but not always. There’s quite a lot of people out there not paying any attention to what Trump is doing. If whatever Trump is doing doesn’t affect them personally, they don’t care. A shutdown may or may not get their attention.
