I think he is very value driven, and wants to be known to be peace president.
Definitely moral idealist.
He thinks before he speaks.
He has very strong language against his enemies, fierce fighter and principled.
Never gives up against all odds, keeps his eyes on the greater good.
Which suggests strong Fi values.
He seems to like phrases like "Think Big", but also is matter of fact, "I say how it is" which means he sticks to what he considers absolute truth even though its subjective and others see it differently.
I also think hes very traditional in sense, a kind of all American guy, he sort of represents what I would imagine a highly successful American business person would look like. Very tan, very superficial, but very talkative, and very persuasive and very committed.
He also seems to thrive in harsh environments, that is when people attack him he does not buckle, but fights back.
Id say his major value is American people. Wants the best for everyone so very egalitarian in sense strong value of fairness and duty for his people, often visits vets funerals and pays respect to veterans, never omits his duty to show respect for poor or underprivileged people.
His economic ideas are driven by vision, of greater America, but he is informed by history, which means he values what has been, and wants to bring back values that worked previously.
He thinks openly, but when determines course of action sticks to it no matter what anyone says.
He has strong sense of fairness and justice, but also frequently points out the flaws in system, like talking about how rich people get away with grabbing pussy, or saying that he could shoot someone and get away with it, in sense he is very aware of disparity between classes of people and often likes to point it out to people who think different.
He also seems to look for rational, like pointing out that electric cars won't work as substitute for gasoline ones, but also makes sure to stick to democratic principal of having a choice, in other words made sure that people can freely buy whatever cars they want, instead of telling people what to do and what to buy.
His also very open to negotiations with Russia, even though Russia shoots US down with every offer, he insist on bring a closure to a massive war conflict often uses emotions he feels in description like I am sad or I am disappointed in Putin etc.
So he often makes everyone know how he feels and where he stands according to values.
So in conclusion I believe Trump is INFP A very stable and very reliable almost like swiss watch, stable genius.
