Partisan polarization refers to the growing divide between political parties, particularly in democracies like the United States. This phenomenon occurs when members of different political parties develop increasingly opposing views, making it difficult to find common ground on issues. As a result, cooperation and compromise between parties become less frequent. This polarization can lead to heightened tensions and conflict within society, as individuals align more closely with their party's beliefs. It often results in a lack of trust among party members and can influence public opinion, media coverage, and even policy-making, further entrenching the divide.
