About 83 Percent of Federal Government Estimated to Still Be Open

Based on a Republican source on the Senate Budget Committee

Everyone knows the phrase "government shutdown" doesn't mean the entire U.S. government is shut down. So in a partial government shutdown, like the one underway at the moment, how much of the government is actually shut down, and how much is not?

One way to measure that is in how much money the government spends. In a conversation Thursday, a Republican member of Congress mentioned that the military pay act, passed by Congress and signed by President Obama at the beginning of the shutdown, is actually a huge percentage of the government's discretionary spending in any given year. And that is still flowing. So if you took that money, and added it to all the entitlement spending that is unaffected by a shutdown, plus all the areas of spending that are exempted from a shutdown, and added it all together, how much of the federal government's total spending is still underway even though the government is technically shut down?
