Cut – The bill provides specific numbers to limit both discretionary and mandatory spending for FY12. These numbers would drive further Congressional action this year or else force a Presidential sequester. (I explain a sequester below.) The intent of this section is to force Congress and the President to cut spending immediately.
Cap – The bill would establish a new enforceable limit on total federal spending as a share of the economy. The new caps are designed to phase federal spending down to just below 20% of GDP by FY17 and then hold it there through the end of a 10-year budget window in FY21. Put more simply, this is a new enforceable aggregate spending cap.
Balance – The bill would increase the debt limit by $2.4 trillion after the House and Senate have passed a Balanced Budget Amendment (of a certain type).
