Extreme partisanship can severely impact governance by creating a polarized political landscape, hindering compromise and collaboration. When political parties prioritize loyalty over collaboration, legislative outcomes can stagnate, resulting in gridlock and an inability to address pressing societal needs. This polarization can erode public trust in government institutions, leading to increased cynicism and disengagement among citizens. As partisanship intensifies, lawmakers may resort to tactics such as filibusters or extreme measures, further entrenching divisions. Ultimately, extreme partisanship threatens the stability of democratic systems by undermining productive dialogue and effective governance.
