There is an old joke about a retailer named Fink, who had a sign in his store window that read: "My name is Fink, and what do you think? I sell clothes for nothing." A customer picked up a suit and started to walk out when Fink stopped him and said he owed him $40 for the clothes. “But your sign said you sold things for nothing," the hapless customer replied. Fink said, "My sign asked, ‘What do you think? I sell clothes for nothing?’ It was all a question of emphasis.”
I think of this old joke as I ponder what happened at the IRS when someone decided to question whether groups seeking charitable status were truly charitable or in fact were political. There would be nothing wrong with IRS officials noting the use of 501(c)(4) status to advance political versus charitable purposes by some organizations and instructing employees to watch for this and assure that is not done. That would be their job.
