WASHINGTON (AP) — When House Republicans pass Rep. Paul Ryan’s budget for a fourth year in a row this week, they’ll go on record again in favor of big spending cuts across a wide swath of programs, including Medicaid, food and farm aid and eliminating subsidies for Amtrak and airline flights to small cities.

But a budget is only a non-binding framework. It can promise the sky, but to actually fulfill its pledges requires follow-up legislation.
