One of my favorite political stories dates back to Marvin Griffin's gubernatorial campaign in Georgia about 1958. Governor Griffin's strategy was to have huge barbecues on Election Day all over the state. He figured that if people ate his barbecue, they would vote for him.
The barbecues drew huge crowds, but when the votes were counted, his opponent, Carl Sanders, won.
A reporter asked Governor Griffin what happened. His response was classic: "They ate old Marvin's barbecue, but they voted for Carl."
The lesson is: You can't buy people's favor.
