Wouldn't that constitutional amendment be unconstitutional?If duly adopted, a constitutional amendment becomes part of the Constitution. The Constitution can't be unconstitutional, pretty much by definition. That said, amending the constitution to limit whom voters may choose is a non-starter, and it won't get a majority of Congress nor 3/4 of the states.
The Constitution states that no state may be deprived of its equal vote in the Senate without its consent. What if a constitutional amendment to the effect that the 5 states with the smallest population should have one senator each, and the 5 states with the largest population should have 3 senators each was passed by the required margins in both houses of Congress and 3/4 of the states went through the process of ratifying it?
It should be patently unconstitutional, but who knows if it went to the Supreme Court after Hillary gets to add a couple of new justices?
