Every year, the President submits a budget proposal to Congress. Every year, both parties issue dueling press releases claiming it either destroys essential services or fails to address runaway spending. Almost none of the specific claims are straightforwardly accurate, because the federal budget is enormously complex and routinely misrepresented by people who understand it perfectly well.
The President's Budget Is Not a Law
The most important thing to understand: the President's budget proposal has no legal force. Congress controls federal spending. What Congress ultimately appropriates will look significantly different from what the President requested. Presidential budgets are political documents signaling priorities and setting terms of negotiation — not blueprints for what will actually happen.
Mandatory vs. Discretionary
Mandatory spending — Social Security, Medicare, Medicaid, debt interest — is governed by formula-based laws that automatically determine amounts based on eligible recipients and program rules. It accounts for roughly 75% of federal spending and is not subject to annual appropriations. The President cannot cut mandatory spending through a budget proposal; changes require legislation altering the underlying program rules. Discretionary spending — defense, education, transportation, research — is set through annual appropriations and represents roughly 25% of the budget. This is what the President's proposal actually affects.
"Every budget number you see in a press release has been chosen to make a point. The question is always: a cut relative to what? An increase relative to what? From whose baseline, over what time period?"
Baseline and the "Cut" Problem
One of the most consistent sources of confusion is the difference between a cut from the baseline and a cut in absolute spending. The CBO projects what spending would be in future years if current law and growth rates continue — the "baseline." A proposal to increase an agency's budget by 3% when the baseline projects 7% growth is, in budget parlance, a "cut" of 4%, even though absolute spending increases. Republicans have claimed credit for "reducing spending" by slowing growth rates; Democrats have called any growth below baseline a "cut to essential services." Both framings contain truth and omit truth. What matters is actual dollar amounts and what they will buy in real terms after inflation.
