The Crowley campaign does have an active social media presence though that doesn't mean that a staffer works on it every day. They could be using a post scheduler & setting up a bunch at once.
In any case, I'll be damned if I sign into Facebook just to message a political campaign, but based on other contact attempts: I'm not convinced anyone is monitoring & responding to their email inboxes or voicemail currently.
I'm so fucking curious about this now.
