It is beyond ridiculous to think this is trump’s doing... If trump were to pull this he would have do so before Iowa.
Why? Trumps biggest challengers before Iown were Jeb and Carson. Trump has been pretty good at picking targets of opportunity to attack, especially with allegations that are unprovable and so they are hard to rebut.
So Jeb became a low energy guy. And Carson pathologically diseased like a child molester. And then little Rubio.
So Trump just waited and NE jumped in to attack his biggest threat left standing.
By the way, I’m not that crazy about Cruz either, but Trump’s campaign has taken the low road throughout.
