Which position in Congress is responsible for leading the larger party?

The position responsible for leading the larger party in Congress is the Speaker of the House. This role carries significant authority and serves as the presiding officer of the House of Representatives. The Speaker is typically a prominent figure within the majority party and plays a crucial role in setting the legislative agenda, guiding proceedings in the House, and representing the party's interests both internally and externally.

The Speaker also has substantial influence over committee assignments and can facilitate or hinder legislation based on party priorities. This leadership position unifies the majority party and coordinates its strategies, making it central to the effective functioning of the House of Representatives.

In contrast, the Majority Leader, while influential, primarily focuses on legislative scheduling and party strategy within the House or Senate, depending on the chamber. The Minority Leader represents the minority party's interests but does not lead the larger party. The President pro tempore is a largely ceremonial position in the Senate, typically held by the senior member of the majority party, and does not have the same level of leadership authority as the Speaker.
