- 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- I hesitate to reply “stop” because I don’t want them to know this is a live number (is my instinct here outdated/inapplicable?)
Yep, I looked them up just to see but, like you said, the fact that it exists doesn’t mean anything. I didn’t find anything (good or bad) associated with that phone number - could be spoofed.
