Sadly, once Trump is out of the picture, the establishment parties will be force-feeding American voters more Bushes, more McCains and more Romneys.
The tell will be Trump's VP pick. If he goes with an establishment politician (i.e. Rubio), my fear will be correct. If however he chooses boldly (i.e. Ramaswamy), then MAGA might have some legs going into 2028.
