A powerful advocacy organization has made a big impact on this midterm election cycle in states across the country. Americans for Job Security (AJS) has spent millions of dollars on attack ads targeting candidates they view as anti-free market. While this group believes in the free exchange of capital, they are vehemently opposed to the free exchange of information, at least when it comes to their sponsors. AJS has routinely denied requests for a list of donors. As a 501(c)(6), they do not have to reveal this information. But the IRS has stated that any 501(c)(6) group whose "primary purpose" is political activity, must name their donors. The Washington Post reports that AJS spends the vast majority of its budget on television and radio ads before elections. Groups such as Public Citizen have complained to the IRS about AJS' abuse of its tax-exempt status. But the ambiguous nature of the IRS' "primary purpose" standard has allowed AJS to continue spewing attack ads every election cycle.
