The Blue North Democratics beat the Grey South Confederations in a Civil War over a 'Domestic' issue.
The Blue North proved it was superior at a Domestic level.
The Confederations may have proved superior at dealing with Internationals, but because Politics 'broke down' and War destroyed one half of that 'binary' system. The Confederation aspect in American Politics (when it was formulated long ago, along with Democracy, Liberalism and more) is no longer around.
What we saw is the Blue North Demcrats chasing a weakness (International) and not following their strength (Domestic). Thus they have basically turned themselves 'inside-out' in an effort to cope under modern pressures of a changing world and America.
They 'over-achieved' internationally and thus 'under-achieved' domestically.
They will Politically fail soon as a Party. Democracy, like Confederation - will fail in America. End of the North-South aspect of Politics (The Vikings & Romans

).
The Democrats are hanging themselves basically.
All the Republicans are doing is giving them enough rope to do it.

Just like Great Britain is politically stepping back in Europe because they too are giving France 'enough rope', as France still deems itself the 'Superior' Political nation of Europe. Well, we'll see soon, eh?

So poor Trump, even if he gets back in a President. He'll be basically forced to deal with 'the mess' the Democrats have made of everything. He'll be Great Again - but America will never be 'Great Again' until a White West (Liberals) Party emerges to balance/binary with the Red East Republic Party - after the 'Suicide' of the Democratics.
Out with the South and now North. (Failure of Confederation & Democracy)
In with the East and 'West'

(Success with Republic'ism and Liberalism)
