House leaders are more powerful than senate leaders because of
the majoritarian nature of the house—a majority can run it like a cartel

the constitutional position of the house
the state of the union address being delivered in the house chamber

House leaders are more powerful than Senate leaders because of the larger size of the House.

Explanation:

The leaders of both the majority and the minority in the Senate and the House are the leaders of the political parties in their respective chambers. Due to the size of the House of Representatives, composed of 435 representatives, the leaders of the Chamber possess a power superior to that of the leaders of the Senate, which is only composed of 100 senators.
