You are having trouble with logic - let me help you. The original statement was something to the effect that he is disliked by ANYBODY who has worked with him.
That doesn’t mean he is disliked by George Bush, which I don’t dispute, but you decided to restate. It doesn’t mean that he is disliked by several people who worked with him. It doesn’t mean he is disliked by many people who worked with him. It means that everyone who worked with him dislikes him. In order to prove that statement, you would need to list everyone who has ever worked with him and show that they all dislike him. In order to disprove the statement, one has to produce only ONE person who worked with him who does not dislike him. Rick Perry endorsed Cruz - did Perry never work with him? Lindsey Graham (not that I would publicize that endorsement if i were Cruz) endorsed him - and Linda worked with him in the senate - so that one example proves the statement wrong. I call BS on the statement.
The gist that I gathered related to arrogance or conceit (such as acting like he's the smartest person in the room), and excessive ambition.
I'm sure that's not how everybody feels, but it is possible that such feelings could be higher than the norm. Certainly the blunt statement made by George W. Bush gives one pause...
