For the past couple of months I've been getting a pile of emails from various outfits, all non-political. I suspect some spammer is signing people up for them, including me, so that legit enterprises will receive lots of unsubscribes and spam complaints, letting the actual scammers look "legit" in all the churn. I wonder if you're being hit by a political equivalent. Though I admit it's at least as likely Trump & co are just grabbing all the emails they can for their fundraising.
