I think his knowledge of "business" is massively overblown. Compared to other traditional politicians -- ok, perhaps in certain aspects although even many life-long politicians have at least listened to more detailed descriptions and perhaps toured a wide range of businesses and tried to grasp the issues they face. That is never as good a substitute for first-hand experience, but Trump doesn't have this kind of experience either in ways that translate to many general businesses. Trump knows real estate development, which can be very narrow and unique, and it would be hard to argue that he doesn't know marketing as evidenced by the way he markets himself and his name on other items over the years (although, it does somewhat appear that many of his business-marketing ventures beyond the reality-tv hits have been losers on their own and his financial success has been based mostly on real estate projects). There are thousands of businesses today employing millions in this country who rely on a global supply chain for any number of aspects of their business. He is as anti-trade and anti-global a candidate, at least in his rhetoric, as any in recent memory. Unless you are suggesting (as some are) that he really doesn't believe anything he has been saying and has just been trying to first win the nomination, I don't see this populist preaching as pro-business in any aspect whatsoever. Quite the opposite regarding effects on many businesses in this country.

Looking at your list of "positives", I'd say yes, he knows the media, is generally non-PC (although I'd say he picks and chooses on this one more than people think), and he is the non-HRC candidate (I think plenty of his supporters would identify closer with Bernie if party-affiliation wasn't involved). Quite a list of "pros".
