A surprisingly large share of state legislative seats are decided long before Election Day — by the absence of a competitive challenger. In some states, more than a third of legislative generals each cycle feature only one major-party candidate. These races barely cost money, generate no news, and produce wide partisan gaps in chambers that can look superficially competitive on paper.
This page collects every state-level general election we have on file where the winner was the only candidate on the ballot, or where the nearest challenger received under 5 percent of the vote. Use the chart to see how unopposed-race volume varies cycle to cycle (a function of state partisanship, candidate recruitment, ballot-access rules, and incumbent power), and browse the full list below, filterable by state, chamber, year, party, and whether the winner was an incumbent.

Methodology
A race counts as "unopposed" here under either of two conditions: (1) the winner was the only candidate listed on the general election ballot, or (2) the winner faced opposition but the nearest challenger received under 5 percent of the total vote. The 5% threshold catches races with only token write-in or third-party opposition, where the practical outcome was identical to a single-candidate ballot.
Why include both. Ballot-access rules vary by state. Some states list write-in slots that always produce a "second candidate" with very few votes; others drop unopposed candidates from the ballot entirely (Hawaii does this for some legislative races under HRS §12-41). Counting only zero-opponent races would under-state how often state legislative outcomes are effectively predetermined.
What's not included. Primaries — many of which are routinely unopposed but follow different competitive dynamics. Special elections — where last-minute filing windows make "unopposed" less informative. And jurisdictions like Nebraska's nonpartisan unicameral, where the top-two primary structure makes the general election competitive almost by definition.
Coverage window. 2010 forward. Vote totals and percentages are sourced from the underlying election records — where votes aren't recorded in our database (notably some unopposed Generals that are never reported by state SoS offices because no contest occurred), the race still appears here based on candidate count, but the vote share column shows a dash.
