Resolves based on any of the following:

1. They do a "Why I Left the Left"–style article or otherwise directly state a right-wing pivot

2. Their listed party affiliation changes (or "ideology" tag is added to, if applicable) on Wikipedia, and remains so for over a month

3. Vibe-based Manifold poll following some event suggesting a significant movement rightwards, with the question "Did <x> pivot to the right?" And the answers "Yes," "No," "and "See Results" (A person can be voted on multiple times; NO resolutions will only come at market close).

4. If all else fails, my personal judgement

I will not bet in this market due to its subjective resolution criteria.
