It pains me to agree with you on this point. But at this point in time third party votes are a waste of time.
Not from the leaders of the party's' point of view. They know they won't win BUT they can make a very good living from picking a hot button issue that really resonates with a million or so angry single issue voters and telling them EXACTLLY what they want to hear. They are secure in the knowledge that they will never have to follow through but the money comes rolling in. Pat Buchanan received about 6 million dollars in contributions for TV commercials he never ran. It is one hell of a racket for the right guy that has the knack.
