I have no problem with Trump's brash personality either except as it might relate to his electability in the general election. My concern goes to his very dubious history, to his, frankly, cruelty, and to his incoherent political philosophy.
Because Trump is not a doctrinaire conservative but a blatant narcissist, I question his desire to overcome "the institutionalized repression the GOP establishment regularly facilitates" except and unless the GOPe obstructs his designs.
Nevertheless, I'm now on record as believing that he will be the nominee and I will support him in the general. My phrase is, I will surrender all to this process except my self-respect.
