Political harassment

What do I have to do to get my phone number out of the hands of candidates? I have been inundated by phone calls this past month, as many as six or seven a day. It is extremely intrusive into my life. There needs to be a way to opt out of political advertising over the phone. I can’t get my mail out of my box sometimes due to the volume of the advertising and you can’t get away from it on radio and TV. That should be enough. Voting is my right and I should not have to be subjected to unwanted interruptions into my home life in order to vote. I want them out of my house. Mark Jackson Stockholm
