"I can tell you I'm their worst nightmare"

But Mr. Trump comes from the “no publicity is bad publicity” school of public relations.

“Obviously, I hit a nerve because they’re fighting me,” he bragged. “I don’t hear them talking about Mr. Pawlenty [former Minnesota governor Tim Pawlenty] or anybody else. They are talking only about Trump. I can tell you I’m their worst nightmare. I am not the person they want to run against. They know it and I know it. I know it for a fact because I have a lot of people that frankly are contributors to him and they tell me, Donald, you are not the person they want to run against.”
