Thirty years of dead bills

By Amy Traylor, Editor & Publisher · July 10, 2026

A legislature is often described as a place that makes laws. Looked at across three decades, the New Mexico Legislature is better described as a place that filters them. Of the 48,533 bills in our database, introduced between 1996 and 2026, the great majority went nowhere.

The odds a bill faces

About 29,700 bills — roughly six in ten across the full period — are recorded as having died. In the decades where the records use consistent status coding, from the 2000s onward, the death rate is steadier and higher still: right around 68 to 70 percent in each of the 2000s, 2010s, and 2020s.

A caveat we'll be candid about: bills from the 1990s in this data show a much lower recorded death rate, but that almost certainly reflects how those older records were coded rather than a real difference in outcomes. We flag it rather than smooth it over — and we lean on the consistently coded, more recent decades for the trend.

Passage is the exception. Fewer than one in five bills became law: about 5,500 were chaptered and roughly 3,750 recorded as signed by the governor. Another 1,400 or so passed the Legislature only to be vetoed or pocket-vetoed.

Most bills die quietly

And they die early. Of the bills that failed, the large majority — about 26,800 — died in committee, never reaching a floor vote, as we detailed in a companion piece. The dramatic floor fight is the rare case. The ordinary death of a New Mexico bill is silent, in a committee, without a recorded vote.

The most prolific sponsors

Volume is concentrated, too. A handful of long-serving legislators account for enormous shares of the total. By raw sponsorship count over the period, Pete Campos leads with more than 1,140 bills, followed by Linda M. López (about 1,030), Mimi Stewart (about 960), Cynthia Nava, and Carlos R. Cisneros. Prolific is not the same as successful: bills from even the most active sponsors died at rates much like everyone else's. Introducing legislation is how a lawmaker puts an issue on the record — whether or not it is ever meant to pass.

Why it matters

Knowing that most bills die — and die in committee — changes how you read a legislative session. A bill's introduction is a starting gun, not a finish line, and the real decisions happen in a handful of rooms long before any floor vote. Every one of these bills, and its path, is searchable in the bills database.
