Is Fear a Legitimate Tactic

I think fair is a legitimate tactic in advertising as long as it is true. Its use in political ads has more of an effect on its viewers because it is real. It evokes fear about a real person who represents some area in which you live and has the ability to stay there for a certain amount of years. It is frightening to think that making the wrong decision in a presidential election can affect you for four whole years. I think living in our era, post 9/11, and now dealing with the horrors of an economic crisis, politicians play on fear will increase.
