The impact of populism on mainstream political parties can lead to significant shifts in strategies, priorities, and voter alignments. As populist movements often rise by appealing to dissatisfaction with traditional politics, mainstream parties may adopt similar rhetoric or policies to retain their voter base. This can result in a polarization of political discourse and the recalibration of party platforms to address the concerns of everyday citizens. Ultimately, populism challenges established political structures, pushing parties to reconsider their approaches to governance and representation.
