ProPublica posts a story today quoting the IRS filing by Crossroads GPS, the non-profit group set up by Karl Rove and others, to raise and spend money on elections and, as the documents claim, "public education."

Reform groups have challenged the IRS status of Crossroads and other non-profit groups, saying they don't meet the qualifications laid out in section 501 (c 4) in the tax code. The document obtained by ProPublica shows how Crossroads makes the case for that status.

Fred Wertheimer, who has challenged the tax status of Crossroads, says he is not surprised or impressed by the language in this filing. "If you believe this is a social welfare organization, I have a rocket that can get you to the moon very quickly and at very little cost."
