Some just can't think that far.  The guy grew up with a silver spoon in his mouth, his dad funded him through multiple failures, and he's shown only to be a figurehead in his "empire", surrounded by teams of capable people.  GW Dummy was in a similar situation, and he showed his ineptness.

This outcome doesn't surprise me one bit.  There was one successful, self-made multi-millionaire in this last election (Johnson), but most won't look past that D or R on the ballot.
