The Center for American Progress and its affiliated 501(c)(4) Center for American Progress Action Fund often attack conservative and libertarian organizations as tools of corporate interests. The latter’s Think Progress blog, for instance, has often suggested corporate donations undermine the credibility of CAP’s ideological adversaries. This makes a recent report and follow-up in The Nation on CAP’s own corporate support quite interesting. CAP claims to not be influenced by its receipt of corporate money. That may well be true, but it would be easier to credit such claims were CAP and its affiliates more willing to give others the same benefit of the doubt.
