Assuming that the article isn't quoting out of context (an unfortunate probability) then Trump has just managed to state out loud exactly why I'm not a fan. Everything he's said on the campaign trail and now has indicated that he doesn't really have any hard and fast convictions of his own. He is a populist who doesn't really care about the constitution.
Him not being able to get his way, despite the fact that much of his plan of action is either beneficial, or at least not terrible, is a Good Thing. I know that some conservatives are frustrated by the inability to achieve much, but we have to remember a few things:
The Constitution is not working as it should, but it is still performing its job to some degree. The executive branch has vastly more power than it did during the early days of the Republic, and the fact that it can still find itself stymied, that there are any checks at all remaining on it, is a good thing. We should not have to rely upon the benevolence of a single man, no matter how that man is picked. In addition, Trump's values have proven.. flexible enough that I'm not terribly sorry to see his power limited. In fact, I'm fairly happy about it. I'm not happy that we have yet to repeal Obamacare. I am happy that a determined executive can't just do what he wants.
