Adopting this approach, Albertazzi and McDonnell define populism as an ideology that "pits a virtuous and homogeneous people against a set of elites and dangerous 'others' who are together depicted as depriving (or attempting to deprive) the sovereign people of their rights, values, prosperity, identity, and voice". Similarly, the political scientist Carlos de la Torre defined populism as "a Manichean discourse that divides politics and society as the struggle between two irreconcilable and antagonistic camps: the people and the oligarchy or the power block."
