I'm not saying that state-run election systems can't be interfered with, there's just no way for a single actor to compromise all systems simultaneously from a single point, legislatively or otherwise. Of course those systems can and should be hardened, but arguing that it should be done in a standard way completely ignores the reality of the political system that we're in. That's like going to your boss and suggesting to completely rewrite your company codebase in X language because it's more secure. Theoretically, it's not a bad idea, but the reality is that it doesn't work that way.
