- never signed up for anything like this,
- never donated to or signed up for emails from the DNC, et al.,
- political texts like this come all the time, and
- I hesitate to reply “stop” because I don’t want them to know this is a live number (is my instinct here outdated/inapplicable?)
Not true—I just successfully reported this text as junk. It tries to auto-detect spam, and coming from an email address is one of the signs of that, but not the only one.
