@Maj. Bill Martin
Being called names and not responding to refute the accusations causes people to think the accusations were true.
But you already knew that,didn't you?
@sneakypete Actually, I think a lot of accusations are best resolved by ignoring them, else you permit your opponent to control what you say just by baiting you repeatedly. There's a story that Lyndon B. Johnson wanted to spread false rumours that his opponent had sex with pigs. When an aide told him that he couldn't say that because it's just not true, Johnson replied; "No, but I want to make the son of a bitch deny it!" Because as soon as you say "I didn't have sex with pigs", people are just going to hear the denial and then wonder what happened that prompted it.
But if you do take the time to deny every outrageous thing about you, that still doesn't explain why Trump then has to personalize it.
Nobody else does that, and false accusations about other politicians hardly something unique to Trump.
