This chapter argues that a fourth wave of Polish populism started during the 2014 European Parliament elections, which affected both the presidential and parliamentary elections in 2015. The Polish political system has been significantly reshaped since the transformation process in the late 1980s and early 1990s. The Polish scholarship on populism might be categorized either as theoretical considerations or as arguments as to why certain political parties or leaders in Poland should be characterized as populist. The Polish literature offers some insight into two constituents of right-wing populism namely, Euroskepticism and anti-communism. The media in its treatment of populist actors is considered either as a neutral channel that passively disseminates Populist Party's political ads during election campaigns or as an active participant, reporting and commenting on political actor's statements and activities. Studies by Jakubowska and Jasiewicz indicated that populist attitudes are strongest among citizens with lower education, higher levels of political alienation, and cognitive problems with analyzing complex issues.
