The one-word substitute for a poll taken of voters leaving the voting place that is usually used for predicting the winners is "Exit poll."

• Consensus: Consensus refers to a general agreement or harmony among a group of people, but it does not specifically relate to predicting winners in an election.
• Results: While results can be obtained from an exit poll, it is a broader term and does not capture the specific context of predicting winners based on voter feedback.
• Census: A census is a systematic collection of demographic data about a population, and it is not directly related to predicting election outcomes.
• Exit poll: This is the correct option. An exit poll is a survey conducted with voters as they leave the voting place, typically used to gather information on voter preferences and predict the winners of an election.
