About: Wikipedia def of Populism
Populism is a political philosophy supporting the rights and power of the people in their struggle against a privileged elite. Critics of populism have described it as a political approach that seeks to disrupt the existing social order by solidifying and mobilizing the animosity of the "commoner" or "the people" against "privileged elites" and the "establishment". Populists can fall anywhere on the traditional left–right political spectrum of politics and often portray both bourgeois capitalists and socialist organizers as unfairly dominating the political sphere.
Political parties and politicians often use the terms "populist" and "populism" as pejoratives against their opponents. Such a view sees populism as demagogy, merely appearing to empathize with the public through rhetoric or unrealistic proposals in order to increase appeal across the political spectrum.
