I'll go there with ya. Some jobs require that you are able to be contacted at any given time. I really think this is one of them. I also feel that if you do not want contact, you should not run for elected office. Or maybe he should have two phones - one that is unlisted for his family and one that is listed and only answered by him. Folks that want to contact him shouldn't all have to go through his office. I don't believe in putting stumbling blocks in front of constituents when it comes to contacting their elected officials.
Besides, don't most (or all) your commissioners have other full-time jobs? I'd be willing to bet they don't want calls at work. So when can you talk to them?
