- Under the plurality method the winner of the election is “R”, with 49 first-place votes.
- This is a rather bad outcome, as there are 51 voters that have “R” as their last choice.
- By contrast, “H” has 48 first-place votes and 52 second place votes - a very good result.
- If we compare “H” with any other candidate on a head-to-head basis, “H” is always the preferred choice.
- For example, there are 51 votes for “H” (48 from the second column plus the 3 votes in the last column) versus 49 votes for “R”.
