Populism can serve as a democratic corrective by contributing to the mobilisation of social groups who feel excluded from political decision making. It can also raise awareness among the socio-political elites of popular concerns in society, even if it makes the former uncomfortable. When some populists have taken power—most notably, Chávez in Venezuela—they have enhanced the use of direct democracy through the regular application of referendums. For this reason, some democratic politicians have argued that they need to become more populist: René Cuperus of the Dutch Labour Party for instance called for social democracy to become "more 'populist' in a leftist way" in order to engage with voters who felt left behind by cultural and technological change.
