The attempt to dismiss the tsunami of negative electronic correspondence she received as merely from Trump supporters doesn't fly. I weighed in on her Facebook page myself and I support Cruz (though I would take Trump in a heartbeat over Hillary). They're trying to contain the damage by characterizing it as a feud between Trump and his supporters and Megyn Kelly, when the reality is that a broad spectrum of viewers were repulsed at the entirety of Fox's handling of the debate.
Regarding the "on her knees" comment, I heard Mark Levin play the clip where Trump said this and it was clear to me that he was saying "that must have been a pretty picture" (or however he phrased it) to criticize her for being weak.
