Resolves YES if John Fetterman:
Has a book tour for his memoir, "Unfettered" (slated for release in November 2025),
With 5 or more planned in-person appearances (not including TV or radio interviews without an audience),
and none of them are cancelled due to worries about protesters or "security concerns" (like Chuck Schumer's book tour).
Resolves NO if Fetterman is fettered: If no book is released before March 2026, Fetterman has no book tour, there are fewer than 5 appearances planned, or any appearance gets cancelled due to protestors or "security concerns."
If the name of the book gets changed, it WILL be a tragedy, but won't affect resolution of this market.
