No - he was egotistical enough. A clever man would have realised that being elected President would shove all his crimes and misdeeds into the spotlight and invite investigations into his business practices which could bring him down, bankrupt him, destroy his "reputation" and end up with a lengthy jail term.
Everything up until now, he has gotten away with, using the very same tactic, simply deny everything that went wrong and claim you're fantastic. He got away with his Hotel imperium collapsing, his tv programme and linked ''campus'' not delivering on what it promised, bragging about ''his'' Trump towers now being the highest after 9/11 and probably much more that i forgot to mention.
Destroying his reputation? He already did so himself, but bragged his way out, Bankrupt? i think he lost count on the amount of times he went bankrupt.
No i think he simply didn't have any other choice than to brag his way to the highest position, the reason he succeeded should be the main reason for worry.
