The IRS may be moving to offer some small measure of reform by looking more closely at organizations that are abusing their 501(c)(4) non-profit status requiring that such organizations NOT be primarily for the purpose of political advocacy.
The impact would be significant in that groups like Karl Rove's Crossroads GPS and the Koch Brother's Americans for Prosperity would be required to pay taxes on income and contributors would be required to pay a 35% gift tax on their contributions and could no longer hide under the cover of anonymity.
