South Carolina Under Henry McMaster
Republican · Succeeded to office Jan. 24, 2017 · Now in 3rd term
South Carolina has tracked the typical state almost exactly under Gov. McMaster — No. 23 of the 29 governors ranked — 38 of 50 are rated, the other 9 are early reads held out of the ranking — across 16 categories.
The Executive Summary
Gov. Henry McMaster (R) has held South Carolina's governorship since Jan. 2017; on outcome trends versus the other states, South Carolina sits No. 23 of 29 ranked states, across 16 scored categories. On McMaster's watch, health coverage (% of adults 18-64 uninsured) fell 18.5% → 13.5% while the typical state fell 13.4% → 9.7% between 2018 and 2024. Over the same service, jobless-benefit access (% of unemployed receiving UI) fell 20.9% → 14.0% while the typical state fell 24.5% → 22.8% between 2018 and 2024. In all, of the 16 scored categories with data at both ends of their measured windows, 5 moved the right way on their own numbers and 11 moved the wrong way. These are movements on the governor's watch — shared with the legislature and the economy, and the window includes COVID-19 public health emergency (WHO PHEIC: Jan 30, 2020 – May 5, 2023) and COVID-19 recession (NBER: Feb 2020 – Apr 2020) — association, not causation.

Each score blends where the state stands today with its trend over this governor’s window, vs. the other states with comparable data — 49 in most categories, fewer wherever a state-year is missing. Scores are in standard deviations (σ) — how far above or below the other states this one sits, where 0 is the middle of the pack and ±1 is a wide gap. *thin data (under 3 points).

The Rundown
No. 23 of 29 — below the national average on 10 of its 16 scored categories.
Wellbeing (mean poor-mental-health days of 30). Better than the typical state, though it moved the wrong way: 4.6 → 4.7 while the typical state rose 4.0 → 4.9.
Obesity (% of adults). About the middle of the pack, and moving the right way: 35.4% → 34.6% while the typical state rose 32.2% → 34.2% — opposite directions.
Early literacy (% of 4th-graders below basic). About the middle of the pack, though it moved the wrong way: 38.9% → 40.3% while the typical state rose 34.1% → 40.0%.
Jobless-benefit access (% of unemployed receiving UI). One of the worst in the country, and losing ground: 20.9% → 14.0% while the typical state fell 24.5% → 22.8%. Worst category on the card.
Moved the wrong way on McMaster's watch — 11 of 16 scored categories. wellbeing (mean poor-mental-health days of 30) 4.6 → 4.7; early literacy (% of 4th-graders below basic) 38.9 → 40.3; energy cost 12.44 → 14.23; water quality (% of systems with a violation) 1.37 → 1.53; tax burden (% of personal income) 4.65 → 5.41; gun deaths (age-adjusted deaths per 100,000) 17.6 → 19.5; cost of living 92.24 → 93.75; education 276.4 → 268; air quality 39 → 44; unemployment 3.4 → 4.5; jobless-benefit access (% of unemployed receiving UI) 20.92 → 14.02. 5 moved the right way. Judged by each category's own printed endpoints over its measured years — the score also weighs standing against other states, which is a different question.
Exogenous events inside this window — 2. COVID-19 public health emergency (WHO PHEIC: Jan 30, 2020 – May 5, 2023); COVID-19 recession (NBER: Feb 2020 – Apr 2020). Years these events touch are outliers on several series — those moves belong to the events at least as much as to anyone in office, so they are marked on every chart on this page, and no verdict here rests on a single year.
How this is scored: 60% is where South Carolina stands against the other 49 states today — it is below average on 10 of 16 scored categories, and 40% is which way it moved on Gov. McMaster's watch. The same weighting applies to every governor. Because standing is the larger half, this ranks state outcomes with the sitting governor named — Gov. McMaster inherited much of it, and the movement half is what changed since.
South Carolina’s debt on their watch
context — not this governor’s gradeWhen Gov. McMaster took office in 2017, South Carolina’s state government owed $15.9 billion (fiscal 2016; Census). The latest published figure is $15.4 billion (fiscal 2024 — the Census survey runs about two years behind). A state’s debt is set by budgets a governor proposes and signs, a legislature that writes and amends them, bond votes, and the economy — it is shared, which is why it is context here and not part of the grade. Figures cover the state government only, not cities, counties or school districts — and they count bonded debt, not unfunded pension obligations, which are a separate and often large part of what a state owes. Source: Census Bureau.
And the promises beyond the bonds
Bonded debt is not the whole of what a state owes. Public pension plans in South Carolina have promised benefits valued at $84.0 billion against $39.0 billion actually held — an unfunded gap of $44.9 billion, 46% funded (2022, the latest year published). When Gov. McMaster took office, the gap stood at $50.8 billion (2016). These promises accumulated over decades, under many governors and legislatures — the most inherited numbers on this page — and the figures cover defined-benefit pension plans sponsored by state and local governments for their employees, so local-government plans are included alongside the state’s own.

Integrity Record
facts from official records — not a scoreHonesty is not numerically scored on this site. For a governor, the record that can fairly bear on it is the Adjudicated Record: findings by bodies that cannot reach a party-line verdict — a court of record, or a state body that is evenly bipartisan by rule. A final such finding caps the grade (it never raises it); nothing else here touches the number. The two ledgers that a member of Congress carries — votes against bills they endorsed, and spoken commitments tested against roll calls — do not apply to a governor, who casts no roll-call votes and leaves no uniform speech record; they are named here so their absence is a stated boundary, not a silent gap.
Adjudicated record
the only tier that can cap a gradeRecord search for McMaster: 0 of 3 admitted sources connected, 0 qualifying events. The event feeds are not yet wired, so this searches no events today — a stated gap, not a finding of innocence. What is already fixed is the rule, published before any event: a cap applies only on a final finding from an admitted body (Tier 1 → F, Tier 2 → C-, Tier 3 → B).
- Admitted — Federal court judgments (deception-map offenses) (admitted by rule — event feed not yet wired)
- Admitted — SC courts of record (criminal judgments on the deception map) (admitted by rule — event feed not yet wired)
- Admitted — South Carolina State Ethics Commission (proposed, awaiting confirmation of the cited statute)
- excluded by rule — SC legislative impeachment / removal: a legislative majority is not an evenly-bipartisan adjudicator
What this measures: findings by courts and evenly-bipartisan bodies against McMaster. What it does not: truthfulness of speech, campaign promises, or anything a partisan body decided — those are excluded on purpose. Dispute anything: challenge@politicalgrades.com. Read the rulebook.

Annual-average unemployment rate — the headline economic series, charted in full. The shaded band is its scored window: it opens with the first full calendar year after the attribution lag, so a governor sworn in mid-year starts a year later than one sworn in that January. It tracks through the newest published data. The dashed line is the 50-state median, shown for context; scoring uses the median of the other 49 states.

Each score blends two z-scores against the other states: where the state stands today (60%) and which way it moved over the category’s window (40%), capped at ±2.5σ. The trend is a fitted slope — log-linear, except where zero is a legal value (water quality), fitted linearly and reported in percentage points — measured against the median trend of the other states with enough data in the same window, 49 in most categories and fewer wherever a state-year is missing. Because standing carries the larger share, a positive score does not mean the trend improved: on 4 of the 16 scored categories on this page the two point opposite ways, which is why both columns are printed.
