“…After becoming one of the most stable party systems among the post-communist countries, with electorally and organizationally stabilized parties (the conservative ODS, Christian Democratic KDU-ČSL, Czech Social Democratic Party, and the radical left communists) resembling the party families in Western Europe, the combination of both economic and political crises in the late 2000s and the beginning of the 2010s led to a dramatic decrease in support for the established parties and the emergence of new anti-establishment parties, including the far-right Freedom and Direct Democracy, technocratic populist ANO, and the social-liberal and technocratic Pirate Party (Hanley, 2012). The rise of these challengers undermined the long-established patterns of electoral behaviour structured around the socio-economic conflict of the political right and left and increased the importance of issues such as immigration and populism cross-cutting the traditional cleavages (Havlík and Kluknavská, 2022; Havlík and Voda, 2018). In turn, factors such as increasing voter volatility (Linek, 2014), low levels of trust in parties and party identification (Linek and Voženílková, 2017), historically strong anti-party sentiments and anti-party populism (Havelka, 2016; Havlík, 2019), and the strengthening role of the non-partisan president have weakened the potential of party-based group biases.…”
