I think what's left to be seen is whether Rubio's attacks on Trump will actually benefit Rubio or Cruz. If the base of Trump's support is vehemently anti-establishment, I'd have to think that any voters Trump loses - if he DOES lose any support before Super Tuesday at this stage - are going to Cruz. They're definitely not going to Kasich or Carson.
Honestly as vile as Trump's racist, xenophobic and sexist rhetoric is, the truth is he's far less of an ideologue than Cruz. The thought of Cruz using his Princeton debate skills to convince Americans that he isn't bat**** crazy is far scarier to me than Drunk Uncle Trump.
I've got debate/town hall fatigue already. I can't wait to see Hillary take on whichever buffoon the GOP picks. That is going to be appointment tv.
