Didn’t read it until you asked.
The article does kind of concede that Trump is an incomplete by talking about this being a “first draft” evaluation of him and how he has three three years to go.
Additionally, it’s all just an opinion poll with no provision of measurables upon which the decision is to be based (as far as I saw in my short scan of the article). Opinion polls on “Best” or “Worst” anything can be kind of fun, but I don’t put much stock in them because they are so affected by so many personal variables and biases. They don’t really mean anything. Designed as clickbait for both that agree and those that disagree.
I don’t why anybody would get too worked up one way or the other over that kind of opinion piece personally.
