Obama worked for Acorn and Acorn worked for Obama. That doesn't mean the president is implicated in any wrongdoing, but it suggests at least that the worse things get for Acorn, the more embarrassing it is for him. If the Justice Department fails to prosecute, it invariably would raise suspicions of political favoritism. This column does not care for special prosecutors, but the case for appointing one would seem to be stronger here than usual.
