Trump is a loud, abrasive, narcissistic gasbag.
He's always been this way, well before he ever entered the political arena.
He's always been purposely controversial, everything he does or says is done with a purpose beyond what's taken at face value, much like your standard run of the mill politician. Yet Trump is able to run circles around regular politicians because he's been at this game in the pop culture world for four decades.
I suggest that if you always keep in mind that he is and always will be the narcissistic, bombastic gasbag everyone knows him to be and then always pause to consider his actions through that lens, you'll be less prone to allowing him to get your BP up.
