The description of the Princess says "Once per game, you may publicly declare yourself Princess (by bolding words to the effect of Claim: Princess). The Narrator will confirm your role. Going forward, your vote count at the end of each Day will be set to 0, regardless of how many people voted you. After revealing yourself, the only Night action that can target you is the Mafia kill." The bolded part makes me think it's only votes against the Princess that are affected. Or is there some other part of the rules I'm missing?
