Actually Imelda was just as great a "It's exciting when the little people suffer" savant as Leona Helmsley, but one was in charge of a business and acted locally, and the other was the witch screwing a dictator but had nation-wide access.

Since you asked about Miller or Marjle after saying, "Charles Barkley", I've got to go with:
Marjle
Unlike Charles and Dan, when you think Miller, you don't think, "Well, his Mama thinks he's pretty."
