I would say that Donald Trump (and plenty of other examples) was/is widely recognized as a piece of ****, and he was elected as well. We're talking about the south, 30 years ago, and a lot of people (then and always) will vote according to the "R" or "D" next to a name regardless of the candidate's actual policies, actions, or beliefs. I don't think Jordan supporting Gantt would have made much of a difference, unless it was a particularly close race and he would have brought enough attention to the race to get more people out to the poles. I just don't think it would have been much of a leap or risk to do it, and has probably cost reputation more in the long run, but if that's what your calculation is based on, then are you doing it for the right reason anyway? I don't know.
