The term conservative itself is somewhat meaningless if not juxtaposed with progressive.
It has been my experience that people who identify as conservative are really stating that they are principle-driven in their political reasoning.
They would more accurately be called libertarian or constitutionalist in many cases, essentially lovers of what America was founded upon - individual-based freedom and strictly limited central government.
Trump is neither of the latter two things. To the extent he demonstrates any solid conviction to principle it is in old fashioned nationalism.
Nothing inherently bad about loving your country in general. It's certainly better than border-less one-worldism of the Left. But nationalist principle does not define the relationship between individuals and the government.
Socialists sometimes do the nationalism thing too - as we all recall WWII. Not that I'm making the dreaded N-word comparisons here. Just pointing out that being a nationalist might be fine, but it says nothing about a candidate's respect for my God-given Freedoms. Nor for our nation's other founding principles and documents.
On the other hand, proclaiming that health care and education are primary functions of the central government does show a profound disrespect for those founding principles.
I don't think Trump is a liberal socialist in the same sense as Hillary or Bernie. But in the sense that he does not possess or profess the Freedom-oriented libertarian / constitutionalist principles which would prevent him from considering some of their big-government ideas as somehow good.
Trump believes in the rule of men. As opposed to the rule of law. For example, he doesn't oppose Obamacare as he should on the principles of individual liberty, limited central government, etc. He just thinks it's designed / implemented by the wrong men.
Again, even with all his flaws and his often nebulous basis for his positions, I am voting for him. The fact that he is not today grounded in original American principles is worrisome to those of us who still value them. However, the fact that he clearly does seem to wish well for America is a great step forward from Obama.
