I would argue then that the Senate is extremely overpowered. The disproportionate body should be a brake on the power of the government, not be the literally stronger half of Congress.

The fact that the most democratic part of the US government, the house of reps, is now the weakest part of the US legislature is ridiculous.

If we're dreaming up fixes, I'd say

1) Senate actions should require a strict majority. If anything should require super-majorities, it should be the House of Representatives.

2) The Senate should not be in control of appointments to the exclusion of House of Reps. No idea what the ideal system is there but the disproportionate body should not be more powerful than the proportionate body.

3) The Senate should be able to at most block an action for one term of Congress. That means that every Senate action can be overridden by an election. Which means the disproportionate body is effectively calling a referendum on legislation, instead of being a hard-stop.
