The purpose of a bipartisan bill is to garner support from both major political parties, promoting cooperation and consensus in the legislative process. Such bills can address significant issues that affect a broad spectrum of constituents, facilitating compromise between differing political perspectives. By having cross-party support, bipartisan bills are more likely to pass through legislative hurdles, ultimately leading to more effective governance. This approach fosters a sense of unity and can enhance the legitimacy of the legislative outcomes, reflecting a broader will of the populace.
