How likely is it that election polls can determine a winner?

Because of the natural margin for error and lack of precision in close elections, exit polls on election night are unlikely to determine a winner. Polls are not designed to provide high precision for 50-50 races, making it difficult to predict a race where tenths of a percentage point matter. Therefore, due to the inherent statistical error, no poll can be reliable enough to predict a winner on election night.Also read: US presidential election: How to watch the poll results live on TV, streaming and for free?
