The reason Trump isn’t going to file is because he has, at this point, consulted his legal counsel who have, in turn, consulted the constitutional attorneys they would most likely use to bring suit and have been told: Sorry, Donald. You will lose.
If he files and loses, the most likely scenario, Cruz gets unlimited publicity and Trump looks like the idiot that he is to the whole world.
He will never file. He runs his mouth a lot. That’s about it.
Good thinking and possibly true. Yes, the Donald does have a very big mouth that spews BS most of the time.
He will never file a suit. It is his one issue... why would he destroy it.
