The outrage should be placed with the House of Representatives because they have failed to do their jobs over and over again. Both Republicans and Democrats have failed to follow a clear appropriations process for decades. I think the last time all required appropriations measures were passed on time was 1995 and it had been done only 3 times previous to that. They wrote and made the 1974 Congressional Budget Act law and they can't even regularly function by it efficiently.
It's unacceptable that the gatekeepers of the nation's purse strings can't do their jobs. What we get is a bunch of continuing resolutions and omnibus bills......and deadlines to keep the government open which ends up being held hostage by both sides depending on who is in power and what the nature of the political discourse of the day is.
Congress sucks at their job of funding the nation's business and has for decades. This little pissing match is just like all of the other politicized antics tied to funding the nation's business.
