The myth is everything the Washington Post views in its perverted version of reality.
The GOP Establishment is NOT “the Reaganite Wing” of the party, and there is zero overlap. The GOPE hated Reagan, they still hate Reagan and want to get past the Reagan years, and they always do what they can to prevent Reaganites from taking over the party.
What the GOP Establishment actually are, are the progressive republicans with a lineage back to Teddy Roosevelt’s huge massive government schemes. They are the Mitt Romney and John McCains of the party.
The MAGA Wing does have unique characteristics, however most of the Reaganites and the MAGA are the exact same people. Seeking limited government, seeking Constitutionalism, and seeking a GOP that finally fights against Democrats and the media instead of a GOP that fights the Reaganites.
The GOP-E did not want Reagan to have his pick of Jack Kemp, as Vice President.
They forced Bush, Sr. On him.
