Is the US Senate fair?

The senate is fair. California is proportionally represented in the house of representatives, as well as North Dakota.

The senate was constructed to maintain equal representation for all states in the US, regardless of size.

Yes that is fair. That is in the US Constitution and each state has an equal number of Senators. That disallows large states from dictating to the rest of the country! You get 2 per "state", what is unfair about that. It has nothing to do with population. The Congress however is different!

We don't want California running the country. Seems you have a hard enough time running your own state! You rule by "proposition", exactly what the founding fathers did not want.

California wasn't even a gleam in the eye of statehood when the original 13 "states" wrote the constitution!

Duhhhh ... 2 Senators per State AND x number of Representratives based on population density !!

There is a reason for that. It goes back to Rhode Island vs Virgina/New York. You get proportional representation in the house but that is stolen by the party system that tells you rep. how to vote. You have no say so on voting in congress or the senate!

Pay attention in your civics class. EVERY state has only 2 Senators. The House members are decided by population, 1 rep for every so many 100,000.

The Senate was intended to represent their state's interests, not the people's (that's the House's job), so in that role, the founders thought it most fair to give each state equal voice.
