I think that refers to the ganging-up against him for the past two months. Has it been real? Yes. Has that happened to Cruz yet? No. Will it ever? Yes, if he is lucky. At that point it will be an unfair treatment of Cruz. And you will know how it feels.
Donald Trump is a type of Samson: Doesn’t drink, has wild hair, chases foreign women, gets really upset if the treat him unfairly, really good a slaying Philistines, and brings down the Temple of Dagon.
This is why I say that Donald Trump is a type of Samson:
Judgse 15
3 And Samson said to them, “This time I shall be blameless regarding the Philistines if I harm them!”
4 Then Samson went and caught three hundred foxes; and he took torches, turned the foxes tail to tail, and put a torch between each pair of tails.
5 When he had set the torches on fire, he let the foxes go into the standing grain of the Philistines, and burned up both the shocks and the standing grain, as well as the vineyards and olive groves.
