Trump is incompetent and a poor leader. Think about this, why does not Trump not have ANY non-executive director roles in ANY other companies? Successful business leaders at this level usually hold advisory roles on the boards of other companies, but not Trump. This was a huge alarm bell for me when he first started to mouth off, it was clear (to me) that he is not respected by the business community, his views and advice are not valued, he's not a team player.
He's useless nobody that's worked in any kind of leadership role will find Trump impressive, he's all talk and hot air, a bomb waiting to go off.
