A keyhole speech is very simple, especially mine. First it states the issues. An issue is just a difference of opinion, which is why we put erasers on horse races. And as I always say, as long as we have issues, we can't have everything. Second, the speech goes on to attack the present administration and show how it has ruined the country. Then it goes on to attack the other candidates and show how they'll keep it ruined, and generally builds up a warm and friendly atmosphere.
