SuperPACs must report their donors, actually. But there is a lag between the donation and reporting, so that's temporary anonymity.

And since SuperPACs can accept donations from organizations, listing donors might not be that enlightening. It's not hard to set up a corporation and pass the donation though it, and then the corporate name gets listed as the donor instead of the person.

I'd be a lot more willing to make political donations if I could do it anonymously: not because I care who knows what causes or politicians I support, but because I'm thoroughly sick of the relentless barrages of begging spam you call down on yourself by ever so much as breathing a hint of generosity toward any party-affiliated political operation.

I'd put cash in a bucket at a campaign event, but no way will I ever again use an online donation form.

Unintended consequences, etc.
