Less power in the U.S. Senate than in the U.S. House of Representatives

Explanation:

Every state gets two senators in the U.S., regardless of their population. In the House of Representatives, you get more representatives depending on your population. Ex. California has a population 39 million people, which gives them 53 representatives(I don't know the conversion rate). But a state like Wyoming has only 1 representative.
