I think we should call it the "spoiled toddler" leadership style, maybe the invention of that new style is going to be Bush's legacy
Seriously, all his life he has been insulated from cold reality by his money and family. It's a fact of life for him, like the sun rises in the east. I think his presidency is just a microcosm of his life, where bad outcomes are screened off, those surrounding him are just an extension of his will (as are family members of every coddled child), external controlling mechanisms are dismantled, and failures are abundant and never his fault.
It's his personality. IMHO it's the worst personality you can have in any powerful leader, because you know that he's going to do whatever he wants and is not going to be accountable.
Note that this topic has been touched on in this thread, and it's surprising that the OP link doesn't mention Lawrence Wilkerson, who has argued this point quite eloquently recently:
