That's a pretty bizarre rant. I think if you want to boycott every product based on a one-time use in a commercial of someone you disapprove of, you'll be saving a lot of money because you won't be buying anything.
Sorry - thought this was America where I could make such a choice. I have owned Chevies all my life and feel they made a mistake here and was looking for support. I want the damned commercial off the air. Mellencamp is a traitor!
