- 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- I hesitate to reply “stop” because I don’t want them to know this is a live number (is my instinct here outdated/inapplicable?)
So does replying “stop” apply to the number that texted you, or to the whole company?
Depends. Usually it applies to the campaign. Sometimes it applies to the company. Sometimes it just gets you flagged as a responsive human.
