- 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- I hesitate to reply “stop” because I don’t want them to know this is a live number (is my instinct here outdated/inapplicable?)
For sure don’t in any way respond, just report spam and block the number. Lots of these things are phishing attempts, trying to get you to give personal information (or even money), and aren’t connected to the things they mention.
Follow parent’s advice.
Never, ever, ever respond, even reverse-uno.
Otherwise, you’ve helped them.
