"The butterfly ballot paper became much discussed in the 2000 presidential election. It refers to a ballot paper that has names down both sides, with the punch holes in the centre. In Palm Beach county, Florida, the butterfly ballot design was confusing to many Democrat voters, who mounted a legal challenge against the election result. They said the design led to thousands of people mistakenly voting for the Reform Party candidate Pat Buchanan when they meant to vote for Democrat Al Gore, or spoiling the paper as they tried to correct their mistake."
