That's fair and that's how I usually call him.
In the spirit of the topic, though, when there is occasion to use another name I've been leaning toward Donald the Hutt. You know, as a criminal boss with a tendency to short-change contractors, a horrible temper, an oddly orange countenance, a body swollen from a life of gluttony and indolence, and small hands he insists on forcing on whatever women are unfortunate enough to have to deal with him.
I think it overstates the president's competence, character, and hairstyle, but no analogy is perfect. Here's hoping he, too, can find himself strangled by the chains he is trying to put on others.
