They are telling him that he can't poll watch because those instructions are not for that polling place. How do they know that? Does it say on the form? Did they even look?
I have though this myself. We have seen video after video of people wearing MAGA hats that are attacked. Why would they tell a pollster who they support? Is te pollster just trying to dox them for their support?
This is a good sign.
Trying to motivate people by hating the other candidate will get a few votes, but it won't be enough.
