Rep. Matt Salmon (R-AZ) doesn't think it's the end of the world if other people don't get paid.
If House Republicans force a shutdown at the Department of Homeland Security, 30,000 workers will be furloughed, sitting at home with no pay, while 200,000 workers will keep going to work every day—but still not be paid. But don't worry, say several of the extremist Republicans who are helping keep the House from passing a clean DHS funding bill, it's NBD.
According to Kentucky Republican Rep. Thomas Massie, "It’s not clear what the impact is because there are a lot of things that are supposedly funded anyway, so the impact may be smaller than we think." Hey, as long as people keep doing the stuff, who cares if they're paid?
Reps. Matt Salmon of Arizona and Mario Diaz-Balart of Florida have both said that it's "not the end of the world" if DHS isn't funded, because the workers will keep working. Of course, both Salmon and Diaz-Balart will keep getting their own paychecks, despite having been instrumental in denying paychecks to hundreds of thousands of DHS employees.
Louisiana Republican Rep. John Fleming said "The shutdown would be extremely limited. It would be only in one department, with only a small percentage of people in that one department"—but that's only a small percentage of people not at work. The ones who are working will still go unpaid. Fleming continued that "nobody has a goal here of shutting anything down," but he also hasn't advocated that the House do anything to prevent a shutdown, like, you know, passing a clean DHS funding bill.
House Republicans may or may not care that voters will blame them for shutting down the Department of Homeland Security. They may or may not care about programs that will lapse without funding. But they definitely don't care that, if they shut down the DHS, even the workers on the job every day won't be getting their paychecks.
