Do populist parties lose support when participating in government?

Populist parties typically voice strong criticism of the establishment, but what happens when these parties join national governments? Drawing on a new study, Pedro Riera and Marco Pastor illustrate that populist parties are vulnerable to losing support when they become junior members of a governing coalition. These parties tend to lose more votes when they are ideologically radical, when the coalition they join is ideologically homogenous, and when the coalition holds a majority in parliament.
