So do you take the position that a president can legitimately pardon himself? I don't. I admit scholars seem divided on the question, but the very concept is an assault against equality under the law—I know, it's mangled often enough already, but explicitly giving the POTUS the power to be above the law anytime he's unscrupulous enough to exercise said power ... well, I have a higher opinion of our founding fathers than that. Happily, there's a technical argument as well as a "this is obviously a terrible idea" argument.
