Trump is more of a realist, and sees the multitude of problems in this country brought on by the Greed of elected officials in both parties, and he wants to fix it.
I honestly believe Trump loves America and wants to do the right thing for the American People and to HELL with the Ruling Class and their Corporate Donors.
Becoming President is a Big Step DOWN and a Demotion for Trump. He really has nothing to gain and everything to lose.
I agree. In a very real sense I think Trump does seem conceited and arrogant enough to avoid failing in front of the world at all cost. He feels a huge sense of obligation to give back to the country that has offered the opportunity to be the embodiment of the American dream.
