It is certainly true that the I.R.S., and every other part of the government, should be evenhanded in how it applies the law, regarding liberal and conservative groups alike. If left-leaning organizations were disguising their true purposes to obtain 501(c)(4) status, the I.R.S. should have turned them down, too. And there will also be questions about how the Service, which is an independent agency, answered questions from Congress.
But let’s be clear on the real scandal here. The columnist Michael Kinsley has often observed that the scandal isn’t what’s illegal—it’s what’s legal. It’s what society chooses not to punish that tells us most about the prevailing ethical standards of the time. Campaign finance operates by shaky, or even nonexistent, rules, and powerful players game the system with impunity. A handful of I.R.S. employees saw this and tried, in a small way, to impose some small sense of order. For that, they’ll likely be ushered into bureaucratic oblivion.
