Populist is just what the losing side calls democracy.

See also elitism vs meritocracy.

The difference between populism and democracy is that populists always claim to speak "for the people" even if the people are divided. They'll even take action against the majority and simply claim that all the "real" people are for it.

Democracy isn't rule of the majority; that's tyranny of the majority.

That is how it should be in principle. In this case, the problem is not the political system, it is the politics.

(In other words, you get what you vote for.)

Then secede? Have a majority referendum in your respective states about it and tell us how it goes. Either that or admit that part of being part of the union is agreeing with the electoral college and the outcomes that arise from it.

As much as I think that the majority Democrat States should suck it up about losing the election, I also think it's fully within their rights to secede if their populace wishes.

I am specifically referring to the Brexit referendum, where the majority of voters did vote in favor.
