This paper develops a conception of gaslighting that is absent from popular accounts in the literature, namely, political gaslighting. This conception explains an epistemic injustice inflicted upon an audience by a politician, focusing on value assessments. I will argue that gaslighting is an apt description of the political manipulation that tactfully undermines an audience's epistemic self-trust, in the face of arguments that such manipulation could be explained through other already developed notions, like bald-faced lying or brainwashing. I suggest that a politician’s position of power hands them the capacity to disconcert the audience by repeatedly instilling doubt into the psyches of citizens that their values are expressed in policies they support, until epistemic autonomy is diminished. Political gaslighting is increasingly popular in the post-truth era, and understanding how its effective will help clarify what resistance to gaslighting could look like.
