Elections to the European Parliament: what if more people voted?

Can the rise of Eurosceptic and extremist parties be blamed on the mobilisation of people who previously had abstained from the polls? An analysis of the 2009 and 2014 elections to the European Parliament suggests that support for Eurosceptic parties would be largely unaffected by changes in voter turnout, write Uwe Remer-Bollow, Patrick Bernhagen and Richard Rose. Extremist parties would even have lost vote shares if turnout had reached the higher levels observed at national general elections.
