Urgent: Contact for Our Revolution

If you have a way to communicate with a person in the organization Our Revolution, and are willing to help me make contact, please write to me, rms, at the GNU domain (gnu.org).

I would like to donate to Our Revolution, but I can't find a morally acceptable way to send the donation. The only way they publish is through the web, and their payment system (as is usual on the web) works by sending nonfree software to the user's browser. Running such software is unjust and insecure, so I refuse absolutely — no exceptions, not even for an organization that follows Bernie Sanders.

If I can reach anyone there, I will try to work out a way to donate by check.
