A large portion of the electorate do not have an accurate sense of how big the government is or what it spends money on. DOGE is a living example. They believed (and musk boasted) they'd find trillions in wasted money. I think a lot of people just believe this must be true because they've heard stories in the past. In fact, DOGE found zero waste. Programs they cut were programs they just didn't like. And they fell short of their goals by multiple orders of magnitude. And are now rolling back some of those cuts because they were either illegal or hastily done. The bulk of federal spending goes straight back to constituents in the form of entitlements or to the military or to debt service. Discretionary spending is a fraction of total spending and covers hundreds of vital services. IGs already look for fraud which is pretty rare.
