What this office is

Each U.S. House district elects one representative for a two-year term. Your district is assigned by official maps and your registered address — not by opening a page on this site. The House originates revenue bills, shares lawmaking with the Senate, and can impeach federal officers. All 435 voting seats are on the ballot in 2026.

Why it matters in 2026

Cook’s Partisan Voter Index for the district is D+1, per Ballotpedia. The seat has been a recurring national target. Clark County’s sample ballot is the authority for your district number.

Lee won the June 9 Democratic primary; O’Donnell won the Republican primary the same day.
