Final answer:
The leader in each house of the smaller political party is called the Minority Leader. They are responsible for leading the minority party's activities on the legislative floor and maintaining party order and strategy.
Step-by-step explanation:
The leader in each house of the smaller political party is called the Minority Leader. The Minority Leader is responsible for directing the activities of the minority party on the floor of their respective chamber, may it be the House or the Senate. This leader is regarded as the official head of the opposition within the chamber, and although they may not always hold significant power due to being outnumbered by the majority, their role includes making strategic decisions and attempting to maintain order and unity among their party members. The majority party, on the other hand, elects the Speaker of the House in the House of Representatives and benefits from the leadership of the Majority Leader in both chambers.
