How this race is decided

One-chamber legislature

Nebraska has a single legislative chamber of 49 members, called senators.

Nonpartisan ballot

Legislative candidates appear without party labels, and the top two from an open primary advance, so two members of the same party can meet in November. The forecast uses each candidate's registered party.

Filibuster

Ending a filibuster takes 33 of 49 votes, so a party usually needs 33 seats to pass contested bills; overriding a veto takes 30.

Staggered terms

Members serve four-year terms; about half the seats are on the ballot each election.

Range of outcomes

Final margin across our simulations; the white dashes mark the middle 80%.
