CNN dislikes Trump so much they refuse to tout their own poll, showing Trump beating Cruz by 13% points.
And CNN is the host of the next debate. No surprise there. Plus they want to sway more votes away from Trump by having another Democrat moderated debate. Why do Republicans continue to allow the Liberals to moderate their debates?
Hugh Hewitt has already gone on record that for the short term he expects Christie to come out on top on the next debate. They will not let Rand Paul on the stage because at this point, Rand Paul helps bring Trumps numbers up because they agree on more things than not.
Why is Kasich on the stage but not Rand Paul? Only reason is because Kasichs number one goal is to take down Trump. And they cannot control what Rand Paul says.
