I’d agree that Trump doesn’t have a Republican pedigree, but he did run as one, and as essentially an anti-liberal in nearly all respects, so I think it’s a stretch to say the appealed to “voters from all parts of the political spectrum.”
The question in my mind was whether he meant what he was saying (since he obviously exaggerates in many obvious ways). Judging from his appointments so far, he is serious about “draining the swamp.” That alone will go a long way to fulfilling his MAGA pledge, and I’m quite optimistic at this point.
Ironically, this is part of his appeal to many voters. They're tired of politicians, and they just want someone in office who can get the job done for the sake of getting it done rather than having everything subject to political posturing.
