The Internal Revenue Service was absolutely correct to look into the abuse of the tax code by political organizations masquerading as “social welfare” groups over the last three years. The agency’s mistake — and it was a serious one — was focusing on groups with “Tea Party” in their name or those criticizing how the country is run.
The I.R.S. should have used a neutral test to scrutinize every group seeking a tax exemption for “social welfare” activity — Democrat or Republican, conservative or liberal. Any group claiming tax-exempt status under Section 501(c)(4) of the internal revenue code can collect unlimited and undisclosed contributions, and many took in tens of millions. They are not supposed to spend the majority of their money on political activities, but the I.R.S. has rarely stopped the big ones from polluting the political system with unaccountable cash.
