Final answer:
The real leadership in the Senate rests with the Majority Leader.
Step-by-step explanation:
The real leadership in the Senate rests with the Majority Leader. Unlike the House, the Senate doesn't have a Speaker. The duties and powers held by the Speaker in the House fall to the majority leader in the Senate. The president of the Senate is actually the elected vice president of the United States, but may only vote in case of a tie.
