Trump will certainly answer to his own money.
Being In the billionaires' club he would unlikely be truly representative of the general American populace and would have very skewed views.
A political leader should have a certain amount of diplomatic skill too.
Trump is not renowned for this.
Indeed he could well turn out to be George W. Bush, mark 2 (the less cuddly and more obtuse version).
I remember seeing film of Bush walking into a conference room to give a speech and his opening statement was "Welcome to the haves and the have mores".
Trump would probably be of this ilk.By his background, he could well place too much emphasis on the vested interests of the rich and mega rich and end up ruffling feathers abroad again with foreign policy as Bush 43 did.
