Who is yet controlled largely by similar impulses as other politicians: he is afraid of being embarrassed (on a large scale, politicians generally can live with the small stuff), he is afraid of being caught in a lie, he wants to be liked, he probably aspires to be in some way a reflection of past great politicians (how we all aspire to emulate our heroes), he is probably somewhat mindful of tradition... and other tempering aspects that apply to more stable people, be they conservative, liberal or down the middle.
He's also not particularly influent per se, Mr. Pence. He needs to work with Congress to do all he wishes, which you'd rightfully say also applies to Trump, but I think he'll make less of a public mess of everything while trying to push these things.
My overall point is that I can live with regular conservatives. I don't like it, but we've been through it before and there was still a democracy and institutions at the end of it, not damaged beyond repair. This Trump experiment, I'm not so sure. And this isn't a call to say we'll have dictatorship or anything like it after 4 (8?) years, I think nominally the institutions will still be the same. But what will be their state at the end of it?
