The whole point of running for a party's nomination isn't to destroy the party establishment -- it is to take over the Establishment. That's what happened with Reagan. He challenged the establishment in 1976 lost, then challenged it in 1980, won, and became the guy who controlled the establishment.
“it is to take over the Establishment.”
How do you take over the establishment, when the establishment owns you ?? That’s like borrowing money from the Mafia; he’s gonna be paying the “vig” everyday for the rest of his political life.
