This isn't irony, exactly. But this story from the LA Times detailing how politicians are paying their fines for "campaign ethics" violations with campaign funds is just too choice a reducio ad absurdum to not be something like that. Since "campaign ethics" is itself an oxymoron, I coin the term active oxymoron for this particular practice.
Commissioner Bill Boyarsky, a former [LA] Times editor ... said of the current policy. "I think that really defeats the purpose of the law, that you have broken the law and you are fined, and then you go out and have a fund-raiser with the very same people."Well, d'oh. In fact, the fine may even be paid from the funds that are in question.
