Wouldn't the necessary functions of DHS be better run if they were under a different Department and had to report to those people? And look, I know shutting it down is kind of just inefficient and wasteful, but it does open up to conversation at least to more productive ones like this - do we really need a DHS at all?
I'm afraid it tends not to. When something is threatened to have all its funding suddenly cut off in these congressional standoffs, then there is a rallying effect as both parties talk about how important it is and blame the other that it isn't being funded.
