> Trump is very very different from a mainstream Republican.

The key part of merpnderp's quote is "or agrees with any of his policies". There are tons things that are perceived as "Trump's policies" (and some are in fact his policies) that are just mainstream Republican policies. Just don't confuse "policies" with rhetoric, because in the case of Trump he says one thing and does another all the time. Of course it's a bit odd to me that people who think he's a pathological liar (a viewpoint I can totally understand!) always act surprised when his words don't match his actions...
