Notice your double standard. "Waaaaaahmbulance, it's not FAIR, the other people kept Cruz from his rightful votes!"
Yeah, Trump faced the same crowded field that Cruz did. And beat all of them at the same time.
Cruz won his home state (< 50%) and OK (next to it); he won Utah (Mormon, and Romney friendly therefore GOP-e friendly); and Wisconsin (GOP-e home of Ryan and Priebus...and Walker endorsed Cruz)...and Cruz *still* didn't get 50%.
Plus, Trump has been facing the unified fire of Fox News, the MSM, and hundreds of millions in ads against him from GOP-e influenced PACs, as well as Limbaugh and Levin. Anyone else would have been reduced to smoldering ashes by now.
Incidentally, wasn't it Cruz who won Iowa by having surrogates (like, you know, Amanda "matching tattoos" Carpenter) suggest that Carson had dropped out?
And Trump managed to kick the living sh*t out of Rubio in Rubio's *home state* where by definition Rubio should have been strongest: and Trump took a plurality of the Evangelical voters in the Deep South, which is the only geographic region friendly to Cruz.
Cruz lost Florida and Ohio; he looks like losing Pennsylvania. Were he to win the nomination, he would lose in a landslide just by those three states: and that does not take into account his underhanded tactics with the GOP-e, which may drive off as many as 1/3 of Trump supporters.
Trump has been facing the unified fire of receiving billions of free media from Fox News, the MSM which will reverse to trounce him as soon as the GOP is stuck with him.
