I have never provided my phone number at voter registration. In any case, all the texts to me are marked with "Hello Louella". I have also been "Brenda".

I am not a Louella or a Brenda, more of a "Joe" or "Frank".

I am quite sure that ActBlue just creates a list of names, then create a wardial list and assign those names to a number.

Asking them to stop just confirms your number to work. And yes, it's ActBlue because they have specifically identified themselves as such more than once.

Yes and those are really the only texts I get, as a matter of fact. Various polls.
