Comparatively little work on folk devils and moral panics has focused on mirror image phenomena of collective joy, celebration, and hope. By introducing a theory of "moral euphoria" and the concept of "folk heroes," and focusing on processes of "deification," this article provides a fresh perspective within the moral panic literature, showing how certain actors may go from "folk hero" fame to "folk devil" infamy. Using the examples of Tony Blair and Barack Obama, the article shows how politicians are particularly significant sociological actors in this regard. The conclusion suggests wider implications for the role of academics in demonization and deification processes.The theory of moral panics and the concept of folk devils have emerged over the past 40 years as central analytical tools within sociology, even entering the public lexicon (Hunt 1997). This article does not review existing scholarship or apply moral panic theory to a new case. Rather, it challenges and develops existing theorizing on by focusing on mirror-image social phenomena-folk heroes (not "folk devils"), deification (not demonization), and moral euphoria (not moral panics). And yet, such simplistic binary terms risk introducing unnecessarily crude and polarising language. Rather, this article attempts to understand dynamics that may on occasions stimulate a transition from positive to negative social interpretations. Put simply, this article focuses on transitions from "hero to zero" (or vice versa) in the sense of going from "folk hero" fame to "folk devil" infamy.If this attempt to understand the ebb and flow of social interpretations through a focus on "folk heroes" and "folk devils" (on "moral euphoria" and "moral panics"; on demonization and deification) represents a novel approach that offers the capacity to deepen and sharpen the analytical traction and leverage of longstanding tools of sociological analysis then the empirical focus of this article is also unique: a focus on the politics of moral panics through a focus on politicians. As Flinders recently illustrated, although politicians have traditionally been defined as part of the "moral barricade"-part of the social class constructing the "folk devils" (see also Brezina and Phipps 2009;Hawdon 2001)-recently politicians have themselves become "demonized," with the British MPs' expenses example providing a clear
