A classic example of what Rush Limbaugh used to call a seminar caller--someone who attended seminars held by left-wing activists on how to get onto conservative talk shows to spread disinformation.

However, Ronald Reagan is not a true conservative but a racist warmonger, so I will be voting for Mondale."
