Ezra Klein with the Washington Post channels the sentiment of the Reformers, as the Left searches for a way to explain why the IRS and federal government wrongfully interfered with the free exercise of speech and electoral process from 2010-2012.  According to them, it was wrong to single out the TeaParty because all organizations who exercised their free speech under the law should have been harassed.  This is who the Reformers blame:

The culprit here is partly the Citizens United and SpeechNow
decisions which lifted the contribution limits on wealthy individuals,
corporations, and unions. But it’s also the IRS’s reticence to regulate
the murky world of 501(c)4s — a reticence partly attributable to the
organization’s fear of blow-ups just like this one.

Karl Rove wasn’t the first to try to use the 501(c)4 to solicit
anonymous political donations. But he was the first big player to do it.
And the expectation was that he’d had a clever idea that the IRS would
quickly reject. “A lot of people thought Rove would get smacked back by
the IRS,” says Hasen. “It didn’t happen. And then 501(c)4s exploded.”

Are we really blaming Karl Rove?  How about George W. Bush too!! This episode and the blame the victim attitude of reformers is going to generate a hot fire in the bellies of conservatives and libertarians.  The IRS may be crucified by the Congress, but in the end it will surely survive. However, this anger may spill over to the FEC and the Congress.
