In my experience, political senders change their originating email address (and phone numbers for SMS solicitations) quite often. New ones for each new campaign, making them very difficult to block. I made the mistake of giving my info to Bernie's campaign in 2016 and have been plagued by intermittent ActBlue spam ever since.
