38 of the nation’s 50 governors have enough verified data for an overall rating under Political Grades’ methodology — the rules, including each category’s direction and lag, are published before they are applied and changed only in public, every change versioned in the changelog. 12 governors aren’t rated yet. All 12 of them have no scored category at all: 10 took office in 2025 or 2026, inside the attribution lag; Louisiana and North Dakota took office in 2024 and still have no category with enough post-lag data to score.
The top of the board belongs to Ned Lamont of Connecticut, in office since Jan. 2019, at +0.30σ across 16 scored categories. At the other end, Michelle Lujan Grisham of New Mexico trails the ranked field at −0.96σ across 16 categories. Click either card for every number behind the rating.
Every number on this page can be reproduced from public data — open any governor’s card for the exact series, windows and math, or download the governor dataset. 4 of the card’s 20 categories carry no score: 2 awaiting a defensible scoring rule, 1 deliberately not scored (Honesty — see the Integrity Record), and 1 published as context — School shootings ships a raw count with its own year, never folded into the rating. Adding a category never retroactively rewrites a published methodology version.
