Based on IQ, have we moved from the dumbest president ever, to the smartest?

I don't like the op's set up of this, but
when you look at the brain power required in figuring out important things, predicting events / outcomes, etc.  Than Donald Trump has already surpassed (by a wide margin) Obama in a very short time. 
Not sure what this should be called.  Perhaps "Critical Thinking" instead of IQ ? ? ?

The guy has been so unbelievably prescient, from the Kate Steinle murder, to predicting a terrorist attack in Brussels Belgium, etc etc etc. 

Again, Trump is almost a prophet in how prescient he is. 

Obama has never really predicted anything, identified an important problem, solved anything, etc. 

So, I guess in this sense the OP may be correct. 
We'll see.

We can probably all agree Trump is a Self-actualized person and Obama is not.  Or Trump is much more so than Obama.

to predicting a terrorist attack in Brussels Belgium, etc etc etc. 

Again, Trump is almost a prophet in how prescient he is. 

Who could ever predict an attack on Brussels, the Capital of Europe, the seat of of the European Commission, Council of the European Union, European Council, and European Parliament.?

Lets list all of the people who said the Muslim population living in Brussels would be responsible for a terrorist attack in the month prior to it happening.   
o yea that was Trump alone.
Let's think about all of the people that said he was crazy, racist, xenophobic, "unfit, un-presidential, ill-tempered, etc for saying it... O yea everyone said that.
