How a state bill actually becomes law
The answer
A state bill becomes law through the same broad sequence in every state, but the folk model that "a good idea gets a vote and then becomes law" skips the step where almost all bills die, in committee. A legislator introduces a bill, leadership assigns it to a committee based on subject matter, and the committee decides whether to hold a hearing, amend it, or let it expire without ever bringing it to the floor. Most introduced bills never leave committee. The bills that do get a hearing, then a floor vote in the first chamber, then the entire process repeats in the second chamber, before the bill reaches the governor.
How it actually works
The sequence: a legislator files the bill and it's assigned a number. Chamber leadership refers it to a committee matching its subject. The committee holds hearings, can amend it, and votes whether to advance it. If advanced, the full chamber holds a second reading with floor debate and possible amendment, then a third reading for a final vote. If passed, the bill goes to the other chamber and repeats the committee and floor steps there. If both chambers pass the same text, it goes to the governor, who can sign it, veto it, or in most states let it become law without a signature after a set number of days. If vetoed, the legislature can attempt an override, usually needing a two-thirds vote in both chambers, though the threshold varies by state.1 In April 2026, Kentucky's Republican supermajority overrode nearly all 32 of Governor Andy Beshear's vetoes. Kentucky only requires a simple majority in both chambers to override, an unusually low bar compared to most states' two-thirds requirement, which is why the override succeeded so completely.2
Who holds the power
The committee chair, not the bill's sponsor, controls whether a bill gets a hearing at all, meaning a single person from the majority party can block a bill with broad support simply by not scheduling it. Chamber leadership, the Speaker of the House, Senate President, or Majority Leader, controls the floor calendar, deciding which bills that do clear committee actually reach a vote before the session ends. The governor's veto power is the last checkpoint, and whether that veto can be overridden depends entirely on the state's specific override threshold and whether the legislature's majority party has enough seats to hit it.
Session length and override thresholds vary widely by state. Some legislatures meet year-round. Others convene for only a few weeks or months every year or every other year, which compresses the window for public input dramatically.
