A more democratic America challenge?

What would have been required for a Constitutional amendment providing for the House (and State Legislatures) to be elected by Proportional Representation; the President to be directly elected by Instant run-off; The Senate to have 3 or 5 members per states elected together with Proportionality within each state and some means of reducing the advantages of the super rich in campaigning?

This would require a new constitutional convention.

There is something in the Constitution that says the equal representation of the states (ie. states are all equal in the Senate) is the one aspect of the Constitution that cannot be altered by amendment.

As far as how it would come about I don't see any substantial impulse in America to move in this direction. Oh, the Cultural Creative types occasionally spouts puffs of fantasy that this would cause views more similar to their own to be better represented in Congress but they always fail to realize that some extreme ideas from other corners of the policial spectrum would get into the game as well.

There is an idea in America that our Constitution is Near Perfect and Secred and should be amended only slightly. It is manifest in the theology of John Courtney Murray for one.

Let more of the unwashed masses have a say in government? No thanks. The President chosen by instant run off won't happen, the system, tho considered flawed, actually works pretty good. I don't understand the idea of 'more democracy', we already have enough people that don't participate in it anyway. And as mentioned above, the fewer 'filters' one has the all the more easy something worst will come down the way.
