The impact of populism on mainstream political parties includes the reconfiguration of party platforms and shifts in voter alignment. Populist movements often capitalize on public discontent with the established political elite, pushing mainstream parties to adapt their policies to remain relevant. This can lead to increased polarization, as traditional political ideologies become blurred or redefined. Additionally, populism’s emphasis on direct appeals to the people may pressure established parties to prioritize popular sentiment over traditional political processes. In the long run, this can reshape party dynamics and alter the political landscape significantly.
