Sadly I am on their list, and am subjected to these mailings as well as in-person thug canvassers at my front door (had a kid who worked one summer as a cashier in a unionized grocery store, dontcha know....and am apparently on all of their lists as being a “union household”.
How very annoying! Pity you can't put a sign on your door: "Union pollsters go away! I'll vote any which way I please."
Either that or get a very large dog that growls and barks a lot :)
