Exactly correct. Trump dominated everything. All groups, incomes, ideologies, male, female. It was a historic blowout. What was interesting is that Trump absolutely dominated independents something like 46-6. Cruz cannot and will not win them. Trump even won conservatives and I believe evangelicals in NH. Ted is a regional candidate with some national appeal but not enough to win. SC is not as conservative as the Cruzers would like. There are a lot of northern transplants there and the territory will be friendly to Trump. Trump will win SC big. Very big.
I must observe
Ted Cruz 29,190 votes (-60,175) 11.6%
Jeb Bush 27,890 votes (-61,475) 11.1%
Marco Rubio 26,966 votes (-62,399) 10.7%
Ted is less than 1% ahead of Jeb and Rubio, are they winners too?
I offer two words to support your claim; Lindsey Graham.
