Follow the seat. Keep the evidence clear.

Current names and affiliations come from the U.S. Senate directory, with the Senate XML authority retained for validation. A current party or caucus is not inferred from a previous election’s winning party.

Election outcomes use a frozen public NPR results snapshot tabulated by The Associated Press. A successor is named only when the feed explicitly marks the race called and exactly one candidate as winner. Senate race calls also have individually checked reporting links. AP race and candidate IDs are evidence identifiers, not congressional Bioguide member IDs.

Results snapshot: November 5, 2026, 9:23 a.m. Central. This page does not update automatically. Later calls, certification, resignations, appointments, or seating decisions can change the expected roster. NPR’s AP attribution and election coverage ↗.

The main 2026 Senate cycle has 33 regular Class II contests plus Class III special elections in Florida and Ohio. Each state has two distinct Senate seats. Equal map halves show those seats; they do not show a statewide vote share, land division, population division, or a winner-take-all state.

Two otherwise continuing Class I seats have a separate transition: Minnesota’s Amy Klobuchar and Tennessee’s Marsha Blackburn are governors-elect. Their parties and names are not carried into a purported after-transition roster without verified replacements. They may still serve during the initial days of the new Congress; this is not a January 3-only roster.

Caucus alignment is kept separate from party affiliation. The Senate press gallery identifies current Independents King and Sanders as caucusing with Democrats. Continued alignment is shown for those continuing seats; no caucus or party is assigned to an unnamed appointee.

These are representation and election maps. They do not change the authority or geographic meaning of the site’s 2024 ACS state demographic estimates, and they do not establish that party control caused a demographic or economic outcome.
