Actually it may be true.
Many years ago Jimmah was the governor of Georgia and he was going around the nation giving presentations to other states about zero base budgeting. He was very knowledgeable about all of the intricacies of budgeting.
Jimmah was a great detail man, unfortunately the presidency is not a detail job. It's a leadership job.
Reagan’s degree was in economics, and he was a two term Governor of California a student of the great economists, and a three time Presidential candidate, and had been speaking on the topic for decades, he knew a little about the subject as well.
