He's not a businessman, he's a salesman.

On green energy, I'm getting the impression that some threshold is finally being passed where clean energy is picking up momentum, and won't be so easily stopped anymore. Trump may have promised coal to the former coal miners, but coal is getting too expensive, so that's unlikely to happen. On oil, with some luck, he may want to make the US less dependent on Saudi oil.

So despite his denialism, he might turn out to be okay here. Of course you can never be sure with him.

When has he expressed support for renewable energy? http://www.ontheissues.org/2016/Donald_Trump_Energy_+_Oil.ht...

Or even business like consideration for technology that's rapidly dropping in price? Since the election, he's been making promises to coal workers: https://www.technologyreview.com/s/602853/trumps-empty-promi...

He's not really much of a businessman either, is he?

This reminds me of something that Dijkstra used to do and was criticised for. He used to use [sic] a lot to point out tiny errors that others used to make, implying that the other person wasn't competent. In the words of John Backus, "this guy's arrogance takes your breath away" [1]. In Dijkstra's defense, he might have been arrogant but he had much to be arrogant about.

Perhaps when your bona fides aren't so well established as Edsger Dijkstra, randomguy23, you would refrain from doing the same. We all understood what that person meant. Discuss it and move on without resorting to pettiness.

No. Look at his picks to head government agencies. His pick for the EPA is a climate change denier.
