It won't be pretty if Trump wins and the Republicans maintain control of the House and Senate.
While that would truly be a horror, I'm not at all sure it'd work out quite the way you think it would. Trump isn't really a social conservative. For that matter, he isn't a conservative at all, at least in the sense actual Republican conservatives use the word.
And where other issues are concerned, he's poorly informed and sometimes just plain crazy. So I suspect a Republican House and Senate would end up spending a great deal of their time trying to "handle" him. And would occasionally end up opposing him.
