If a sitting member of Congress announces that they have changed or will change their political party affiliation before 2027, then the market resolves to Yes. The Payout Criterion includes a member switching from partisan affiliation to independent, or independent to a given political party. This Payout Criterion also includes a member of Congress announcing that they will run for the next Congressional office, or in another future political campaign, in a different party's primary. For purposes of this Contract, partisan affiliation encompasses national party affiliations, and does not encompass regional political party affiliation. For example, a member announcing that they intend to join the Democratic Party instead of the Democratic-Farmers-Labor Party will not satisfy the Payout Criterion. This market will close and expire early if the event occurs.
