GfS's choice of "Hitlary" is a deliberate combining of the names "Hitler" and "Hillary", Poppa Gator. Seems to me that if you want to do that, then "Hitlary" works far better than "Hitlery" would, since the suffix "ary" links better and more obviously to Hillary than the suffix "ery" does. This way both names get more or less equal coverage, which is what it's all about when you're combing two existing names into a new word.

Not that it really matters...but I can't figure why you would criticize GfS's choice of the acronym in this case. It works.
