There is no way this is happening. The logistics alone will be killer and as bad as things are, there is nothing that would be gained by this that would be worth the pain it would cause.

To the extent that there are geographic differences, it is not between red states and blue states, but rural vs. urban. Even in texas the major cities almost all go blue.

If by "UNDER HALF" you mean who voted for him then I don't know what you are talking about. Trump won the electoral AND the popular vote. And don't go counting non voters as against Trump.

By every metric the US wanted Trump and they got Trump.
