I think he's pretty clearly ESTP and he's basically the posterboy for the MBTI 16 "ESTP" ie Se-Ti at that.
The argument for him being a Te lead is defeated by the simple fact that Trump doesn't care about what makes external logical sense, he doesn't include other people in his decisions, he doesn't look outwards towards what is going to be accepted as logical - Trump looks within Trump for his decisions - meaning, his decision making process is introverted, and he looks at what makes the most sense to him - though, he does have a very solid understanding of what will have the most impact with regards to the wider social spectrum of Feeling so it's not like his F is non-existent - and, it's clearly extraverted.
That said though, does Trump actually make decisions in accordance with social values? Nope. Like I said. Trump looks to Trump for his decisions.
Ergo, his introverted Thinking is preferred over his extraverted Feeling.
With regards to S/N - there's not a whole lot to talk about here, N is obviously his biggest flaw - he can't see what's coming, he simply can not connect the dots and project his imagination into the future - he is the posterboy for the silly MBTI "Se" stereotypes whereby someone is so wrapped up in the present moment they can't see anything else.
Trump gathers too much information than he knows what to do with, hence why so many things he says are untrue or have a very very tiny amount of truth in them - so he's gathering real-world facts, but he's not making any sense of them at all, he's not comprehending and understanding the information.
So due to the above, I place him as Se over Si - Si types, due to introversion, mull over known information *more than* people preferring to take in more and more and more information (Se/Ne).
So for the reasons above, Trump is a stock-standard MBTI 16 types SeTi type, imo.
His information gathering process is Sensation, and it is extraverted - this is cross-checked with an inferior intuition that is found within him failing to project anything into the future, he can't do anything non-tangible, there's a huge disconnect between Se and Ni with this guy.
