This rivals being beat by a dead guyhttp://www.boscosbonesandbrew.com/
The story was reported worldwide how two men lost to a dog named Bosco in an unofficial Mayor's race in the town of Sunol. No one realized that prank in 1981 would make the town of Sunol so famous! From then on, people just accepted the fact that Bosco was the Mayor.
On July 24, 1984, the Star newspaper wrote an article about Mayor Bosco. The article said he ruled with an paw, took grafts from all businesses in town, in the way of beef jerky (which was his favorite) and dog biscuits.
Many news articles had been written about Mayor Bosco, and he had appeared on television numerous times. Even his death in 1994 was on television as well as in news print.
I have heard of dead people voting Democrat, especially in Chicago, but never a dead person winning.
