The rise of populism significantly impacts traditional political parties by shifting the political landscape. Populist movements often capitalize on public dissatisfaction with established parties, leading to a decline in their influence. This can result in a fragmentation of the political system, as traditional parties may struggle to adapt to new voter demands. Consequently, they might adopt populist rhetoric or policies to regain support, further altering their foundational principles. Ultimately, this shift challenges party stability and could reshape future political dynamics.
