If the Pit-Hag turns an evil player into the Politician, they can't turn good due to their own ability.

The Politician might register as evil to the Vizier.

The Demon cannot have the Politician ability.

A Politician who successfully makes the entire good team believe that the Atheist is evil and manages to get them to execute down to final 2 can be the only player that wins in an Atheist game.

Cannibal/Philosopher/Pixie: With multiple Politician abilities in play, there can be multiple players playing for the evil team. However, only the most responsible player can change teams, so they're in direct competition with one another. If any of these die while they have the Politician ability, they maintain the ability even if dead and can change alignments to win at the end of the game.

The Politician's changing alignments is decided after the Heretic impacts the result of who actually won the game.

It's very rarely fun to make the Politician the good twin as they can campaign for their own execution, never mentioning that they're a twin, then win the game with evil as a result (it's pretty hard to argue they weren't most responsible in that situation!)

Fearmonger/Leviathan/Mastermind: If the game ends due to the Fearmonger ability targeting the Politician or the Politician being executed second in a Leviathan game or on a Mastermind day, the good team loses. If you think that the Politician was nonetheless the main influence in causing this to happen, the Politician can change alignments and win with the evil team, this does not then cause the evil team to lose instead, the game end condition was already evaluated.

Politician/Legion is not a fun combination - the Politician is incentivised to vote on literally any execution but their own and be the single good vote Legion needs to pass every vote – again it's difficult to claim they weren't most responsible here.

The Politician can say the Mezepheles word and then betray the evil team to win with good - they're not restricted to only switching from good to evil at the end of the game, it's also legitimate for them to switch the other way.

If a Politician is in a Revolutionary pair, it's the Politician who must be most responsible for the game end in order to potentially flip both players' alignments, not the pair as a duo.
