I don't get that.
You make a valid point about the Senate and the EC elected president.
The Senate was set up to be anti-national government...a protector of the States, and a protector of Federalism, which is anti-national-majoritarian. The populists chipped away at that with the 17th Amendment. The filibuster is eliminated now, so the Senate is more majoritarian than it ever was.
Now, in blue states, you have Democrats who are willing to sacrifice the votes of their own citizens to get a national majority (and effectively do away with the Electoral College without a constitutional amendment).
We are moving toward perpetual urban rule. And, that is the question: Do we want perpetual urban, hand-out oriented rule. When that becomes obvious, the Union will go the way of the USSR, and break up into multiple countries, and that will be sad. Unfortunately, I think the Democrats will push and push until that happens.
