Ah the Senate.
The Senate gives out-sized power to flyover-state-dwelling yokels. I propose consolidating some of the less-populated areas into new states. Example:
Combine Idaho, Montana, Wyoming, North Dakota, South Dakota, Nebraska, and Kansas into a vast new state called Evangelica that gets two Senators. Residents of Evangelica couldn't really complain about their decreased power in the Senate, because they still have much more than people from a lot of US states. They could focus their new state government on issues important to people in that region, like erecting Christian monuments on public grounds and legalizing torture conversion camps for gays, but their federal power would dwindle to a more appropriate level.
Some other consolidation options:
