As of 2025, there are nine Senators who joined the US Senate before the year 2000. Who will be the last to leave?

If there is a tie, resolves equally between them.

• Update 2025-05-10 (PST) (AI summary of creator comment): This market resolves based on uninterrupted tenure that commenced before the year 2000.

  • A senator is considered to have 'left' for the purposes of this market when their continuous period of service, which began before the year 2000, ends.

  • If a senator whose service began before 2000 leaves the Senate (thereby ending this specific uninterrupted tenure) and is later re-elected, this subsequent period of service does not make them eligible again or change their 'leaving' date for this market. They are no longer in the running once their initial uninterrupted tenure (that began pre-2000) concludes.
