John McCain keeps calling us, how can we make him stop?

We keep getting autodialer phone calls at dinnertime with the recording "Hi, this is John McCain..." in his whiny voice. WHY??? We don't give a hoot about politics schmolitics, have no party affiliation, are not registered voters (and if we were, we sure as $#!+ wouldn't be voting for this clown). How can we get him to STOP?
