What legislative practice involves reciprocal agreements between legislators for voting purposes?

The correct answer is logrolling, which refers to the practice of exchanging favors or concessions between legislators. In this context, logrolling involves two or more legislators agreeing to support each other's proposals or initiatives, particularly during voting. This strategy is often employed in legislative bodies to secure the necessary votes for passing bills that may have a broad range of support.

This practice is particularly effective in situations where representatives have differing priorities but can find common ground through collaboration. By agreeing to support each other's requests, legislators enhance their chances of successfully advancing their individual agendas and can create a more cooperative legislative environment.

In contrast, cloture is a procedure used to end a filibuster and close debate on legislation, while a filibuster itself refers to the tactic employed to extend debate and delay or prevent a vote on a bill. Delegated powers, on the other hand, refer to authorities specifically granted to the government by the Constitution. Thus, logrolling stands out as a distinct practice focused on mutual legislative support.
