For John, BLUF: Planning needs to start now. Nothing to see here; just move along.
Perhaps in honor of the Late Yogi Berra, we have, from the Committee for a Responsible Federal Budget, "Everything You Should Know About Government Shutdowns".
It’s déjà vu all over again, again – Congress seems to be ignoring the gathering fiscal storm clouds. The most immediate of these is just around the corner: if lawmakers do not pass legislation to fund federal programs by September 30, the government will shut down.Not everything shuts down when the US Congress fails to pass a budget or when the President vetoes budget legislation and Congress is not able to override the Veto. But, a lot of things do shut down. The elderly will still get Social Security. On the other hand, certain Federally funded social services will fall on the States.
By the way, it is more complicated than passing of a budget, although there is a Budget Resolution. Then comes a two step process, the Authorization and the Appropriation. We need both for a Federal Agency to expend funds.
