I don't think FR could ever be a 501(c)(3) or (4) - the restrictions on the sorts of political activities that 501's are subject to would pretty much kill it.
Just to reiterate, I never asked for the balance sheets, or detailed expenditures, or anything like that - just a general sense of where that money was going. Anyway, hard to disagree with anything you've said here, Dan. Thanks.
I know C3's are restrictive to no politics. C4's can lobby but not "endorse".
