Identify one difference between the House and Senate that contributes to legislation passing in only one chamber, despite unified party control. Explain how this difference accounts for legislation passing in only one chamber, even when the same party controls both chambers.

Filibuster

Explanation:

Unified party control means a single party being in charge of the White House and the two legislative chambers.

Filibuster is common with the legislators. It’s often used as a delay tactics by speaking extensively about a subject topic thereby obstructing progress in the legislative chamber without technically infringing in the laid down processes of the chamber.

Senate filibuster allows a senator on the floor

2.Prevent/delay other business from being conducted.

This is the reason why some laws aren’t passed despite having a unified party control.
