However, many people who say this do not have a complete grasp of the full mathematical picture – or worse, they are only mentioning the part that supports their position. First let's define what a "wasted" vote is.

Mathematical Definition of Wasted Votes

A wasted vote is a vote that provides no determination or effect on the final outcome of the election. According to Wikipedia: "Wasted votes are votes cast for losing candidates or votes cast for winning candidates in excess of the number required for victory. For example, in the UK general election of 2005, 52% of votes were cast for losing candidates and 18% were excess votes – a total of 70% wasted votes."

There are two kinds of wasted votes that mathematically have no effect on the final election:

Votes cast for candidates who did not win

Excess votes cast for winning candidates
