Ballot Box Bunny

Yosemite Sam is running for mayor, and one of his campaign promises is to get rid of all the rabbits. When Bugs runs against him as the "pro-bunny" candidate, Yosemite uses a number of elaborate stunts to eliminate his opponent (which all backfire). In the end, they're defeated by a dark horse candidate (an actual dark horse!).
