Parts of the government that will shut down include popular DOI departments that a lot of people appreciate: FDA, national park service, EPA, United States geological survey, etc etc
You know, government researchers and ecologists. People that overwhelmingly do not vote republican.
These shut downs hurt civil servants that are the actual machinery that makes the government work, while congress has their collective feet in their collective asses a lot of the time.
It’s deeply wasteful. Federal employees get backpaid for shutdown time. The government still has to meet contractual obligations. Work is left unfinished.
Might feel like schadenfreude, but you’re totally off base of you think the government employs primarily republican voters. The US government is larger than the DoD (by the way, the military will still be paid through the shutdown most likely).
