I'll give this a real shot. Although I don't agree with the way he's gone about either, he has some legitimate points regarding regulation and immigration. I'm not sure if he really followed through on that whole "for every new regulation two existing ones have to be eliminated" thing. In general, we should be looking to make the regulatory framework easier to understand and to comply with. Constantly adding new regulations makes it very difficult for smaller companies to comply. It's just too complicated, even if companies are trying to do things the right way.
One immigration, I'm not so sure that some merit based system isn't a decent way to do things, at least for a portion of our immigration. Also, some pause on allowing immigrants from some of these hotspots isn't a bad idea. Now, he once again didn't go about it the right way, and he comes across as racist, but there is some common sense it really taking a harder look at who we allow into the country.
