That’s what got me fully aboard the Trump train as well.
I was leaning towards him for a while, but still undecided, but it was the refusal to go along with the-way-we-do-things that made me sit up and pay attention!
When he said “no” he proved to me the opposite of what others had said.
They said that he was in it only for the power, and had to get that power any way he could.
But even cursory examination of the opposite answer (The answer given by everyone else) shows that THEY were only in it for the power.
To say that you want “Make things better for everyone” and then stop at the moment you realize that you may lose, you may be inconvenienced or you may lose tells me that your intents aren’t good.
Those other guys wanted power within the party. Thats all.
