Not like a president has a whole cabinet of advisers or anything...
Leaning entirely on advisors is supposed to be a shaky, last-ditch comfort when an idiot is barreling towards the presidency. The candidate actually has to have an idea of what they are doing or they won't even be able to effectively manage all the advice they are being given. If the candidate doesn't know diddly, how will he/she know if they are getting bad advice? How is Johnson going to talk to world leaders when he has no idea about anything? They'll steamroll right over him.
Seriously that is like one of the weakest excuses for justifying putting a know-nothing into the freakin'
White House.
