I don't know how CREW obtained the returns. However, I doubt whether they were put on to public display by the Norquist crowd.
There are, of course, non-profit organizations that are have ideological viewpoints that run counter to those of Norquist. One of them is OMB Watch. A quick trip to their website offers a strong contrast to the Norquist sites with respect to transparency.
On the OMB Watch site, one can:
- Examine the organization's Form 990 tax returns for the last 8 years
- Find out where OMB Watch obtains its funding
- Obtain a list of groups affiliated with OMB Watch, something that Norquist's groups attempt to hide.
To the extent that groups such as ATR and the ATR Foundation obtain indirect public subsidy via the tax code, they should be required to disclose their sources of funding and the ways in which they spend their money. Of course, don't hold your breath waiting for Norquist to make voluntary disclosure.
