Idea: 10 biggest states get 3 senators

[LtNOWIS]

If you have the political capital to do this, why not go all out? I fail to see the point of any half-measure that takes a constitutional amendment.

It can't even be done with a normal constitutional amendment. The constitution says you can't amend the constitution to deprive states of their equal representation in the Senate without their consent.

It'd be easier to change the Senate to something mostly ceremonial like the British House of Lords.
