Partisanship significantly affects judicial decision-making by creating divisions among judges based on their political affiliations. When judges align with certain ideological beliefs, their rulings can reflect those biases, impacting cases that involve contentious issues like abortion and gun rights. This partisanship can erode public trust in the judiciary, as citizens may perceive decisions as politically motivated rather than impartial. Additionally, the confirmation process for judges often becomes a battleground for partisan conflict, further reinforcing the influence of political affiliation on judicial outcomes.
