There are several factors in US politics that led to Trump's election (including foreign involvement), and none of them are "Trump was someone who was qualified to be a capable leader." Whether it's the anti-intellectualist trend that lurks in some segments of the US population, or the way that the Republican party successfully intertwined themselves into American religious institutions several decades ago to make Republican party loyalty be perceived as an odd form of "cultural-Christian" piety by many who were swept up by the "religious Right" and "moral majority" movements, or the straight-up disinformation campaigns targeted at the most willful audiences....not one factor was tied to Trump being a good people leader or an intelligent strategist. It's more that he was the guy that happened to be there when a confluence of other efforts came to fruition, and he was crazy/manipulable/stupid enough to be useful for the role of "candidate".
