What Trump says is often true. His delivery, however, is very off putting to many people. Too bad there isn't a course he could take on delivery...and learn from it. That could win him votes. I have a friend that is so eloquent is his rebuttals, a person will take note and consider what is being said instead of rolling their eyes.
Example: He was in property management. He had to write a letter about cleaning up after your dog when walking it, if you catch my drift. Damn if I didn't want to go pick the dog poop myself, lol.
The sad fact is, he is a politician running for office. What his true believers find endearing the bulk of voters find petulant and bullying.
