I think real fascists would be embarrassed by him, because he isn't good at politics.
He wiped Bush, Cruz, and even the superstar politician Rubio off the map, spending a fraction of what they did in doing it as well.
Say what you will about his views, many of which I personally find refreshing, but saying he isn't a good politician flies completely in the face of the facts of this election cycle.
That Trump could avoid the bad press if he wanted, but doesn't, suggests that he welcomes it. And, to his credit, it seems to be working for him. He's been able to harness a sense of mass disenfranchisement and anti-establishment rage that the Republican Party has been unable to tap into, despite their best efforts.
