He's only defied expectations within his own party. The U.S consists of more than the republican party; You have independents, third parties and the democrats. So sure, he'll have those hard right neocons voting for him, but what about everyone else? What about the moderate (disenfranchised) republicans? Or the independents and democrats? I'm sorry, but I haven't met a single independent or democrat who said they'd vote for Trump. He's about as polarizing as they come. He'll get creamed in the general election. I'll go so far as to say that it will be the biggest landslide in history. I'm talking double digits.
