Jeff's almost certainly correct on this. It would be nearly impossible for either of them to maintain a license and voluntarily surrendering it is the appropriate procedure. It's the same in medicine. It is best to go through the process of this rather than fail to maintain continuing education and get suspended for that reason.
As for the racist hate as a motivation? Maybe, or maybe not. It's an easily condemnable assumption that makes for a convenient derision of the author, but is not necessarily true. I was once accused by a classmate for being racist after calling him out for not pulling his weight in a small group project in medical school. My reply was something like "This has nothing to do with your race, it's strictly personal. You are a worthless lazy piece of shit. I never said you represent your race, but if you did they should all collectively kick your ass."
I'd gladly vote for Condoleeza Rice, Colin Powell, and possibly Ben Carson. I can't stand Barack Obama. It's strictly personal.
