"I have tried to find a phrase in which to define what the Republican Party has done at home. I have said we were "progressive moderates." Right at the moment I rather favor the term "dynamic conservatism." I believe we should be conservative. I believe we should conserve on everything that is basic to our system. We should be dynamic in applying it to the problems of the day so that all 163 million Americans will profit from it. So for the moment I would say the record at home has been dynamic conservatism. You can go into the fields of agriculture, of the freedoms that have been restored to our economy, to the tax system-to everything we have done."
