Political text messages increase dramatically during election season. This article explains why you might be receiving these messages and how to block election text spam from politicians.
How to Stop Receiving Political Text Messages
There is no Do Not Call Registry that would stop political messages sent one by one via P2P technology.
Since you know where the message came from, there's an easy way to stop future unwanted messages: reply to the unwanted text with some variation of STOP, Unsubscribe, Cancel, Close, or Unsubscribe.
You will likely receive a confirmation message that you have been removed from the list. You will need to do this again for each campaign that contacts you. You may need to unsubscribe from the same campaign several times, as your phone number may be on multiple agents' phone lists.
