Yay personal attacks!
There is a difference between being an asshole and being an asshole on tv/radio/twitter.
The only way LBJ was same as Trump would be, if LBJ went on TV everyday and yelled profanity and called people names.
Because that is what Trump does when he rage-tweets every morning.
LBJ was a well known asshole on every medium that was available to him.
Does Trump use a lot of profanity? I've never really noticed. What I notice is that he makes fun of his opponents a lot, but I don't really see how that is considered rude, when his opponents are doing the same thing back to him.
