I don't think Trump will be a Rand/Ron Paul-type clone.
He cancelled the Iran nuke deal, I"ll bet Rand and Ron would NOT want that.
I do keep a cautious eye on Trump in some aspects, I won't enumerate them but I can give an example, this in Syria where he seemed to impulsively state we'd be out in 60-90 days, that was an extremely poor decision and as we know, Mattis walked because of this. Dumb, an inept and uninformed decision. I was ready to dump him until the reversal seemed to come rather quickly.
Nato, Ukraine, I have my concerns. Like Mattis said too, we need our allies. We'll see, I hope, for example, a president couldn't unilaterally cancel membership in Nato. I can see a president trying to enhance our position in saying, "we dl all this, don't we deserve more consideration" and things like that.
