How this race is decided

Two senators per district

Each of the 17 Senate districts has two senators serving staggered four-year terms, so one seat per district is on the ballot each election.

Simple-majority veto override

A majority of the members elected to each chamber can override most vetoes; budget and spending bills need two-thirds.

Range of outcomes

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