When somebody says “I am a conman so I know con men and trust me THAT guy is a conman”, only an idiot would trust you. You just admitted you are a conman. Why would anybody trust you on anything?
I am not saying that Trump is not a conman. I am only saying that your history of spending your life lying, to hock useless crap, makes you nothing more than a modern day street mountebank. You are, therefore, useless for providing reliable insight on anything.
