This type of poll explain why, on election night in 2000, news reporters and journalists claimed that al gore won the election.

Where's the poll and the question, so that I may help you?

The war devastated Korea. Historians said that between three million and four million people were killed, although firm figures have never been produced, particularly by the North Korean government. As many as 70 percent of the dead may have been civilians

Hope that helps :)
