And he has the personal business history (made billions means he is no dummy) to show he has gravitas. He is already 'proven'. Most running for office have proved nothing. How is a lawyer who was in the senate proof they will be a good leader? A CEO like Trump has lead complex businesses in good and bad times and came out ahead. That adds weight to his insults. If Trump calls you a dummy - what proof does a politician have they are not? A law diploma?
Gravitas? He had to say he was “very smart” 23 times at a recent sppech? That’s gravitas? He’s a socialist bufoon.
