Ever heard of Dick Tuck?
Found this:
As Nixon's political star began to rise, Tuck continued to torment him. In 1956 Nixon was running for reelection as Eisenhower's Vice President. The Republican Convention was being held in San Francisco that year, and Tuck learned that the route taken by garbage trucks going to the dump led them right past the convention center. Therefore, Tuck paid to have all the garbage trucks bear signs that read "Dump Nixon".
