Hillary wants the alt right to take over the right, to become the Republican party.
Which means that the alt right gets all the lovely beltway gravy that the Republicans are getting today – and like the Republicans, gets no power. Like the Republicans, becomes the outer party.
The Republican party then becomes the white male party because white males are about to permanently outvoted and rendered politically irrelevant.
It is an improvement on the current plan of the Republican leadership, which is that elections from 2020 out consist of the Republicans saying “White males are hateful, evil and deserve to suffer”, and the Democrats saying “White males are really horribly hateful and evil and we are going to make them suffer even worse”. And the beltway gravy will be nice.
But remember. Demotic politics is never where the power is, it is just theater to manufacture legitimacy for rulers, never a source of power. It can, however, be a source of beltway gravy, which is not nothing.
The booby trap is that we will rationalize pursuit of the lovely beltway gravy by coming to believe, or at least pretend to believe, that demotic politics is where power comes from. The alt-right taking over the Republican party is not the booby trap. The alt right being exposed to the same incentives as the Republican party is the booby trap.
