In de schaduw, uit de schaduw

In the shade, out of the shade. Origin, nature and possibilities of shadow elections or exit polls There is a lot of polling in the Netherlands, especially in the run-up to elections. The assessment of future voting behavior in the run-up to elections is inherently difficult, because many voters do not know in advance whether they will vote, let alone for which party. There is therefore constant debate about the quality of these surveys. However, there are also polls that are not held prior to elections, but on election day instead. They are called exit polls or shadow elections. The sample consists of voters who actually visited the polling station and cast their vote. In this article the authors emphasize the nature and useful and interesting role of exit polls. Exit polls are an important tool for making an accurate prognosis of the results shortly after the closing of the ballot boxes. Secondly, an exit poll can provide further insight into electoral gains and losses, and thus counteract unfounded speculation. After all, the data collected form an empirical source for a first analysis of the outcome and electoral behavior. All in all, the exit poll is a relatively easy-to-organize and attractive ingredient for a results evening. Confusing pre-election polls with exit polls probably does not do justice to the higher quality of exit polls in terms of prognosis. The article explains where exit polls differ from pre-election polls and what the most important choices are when setting up such a poll; it also shows that a well-designed exit poll is accurate and has adds value to a results evening. The authors give practical examples in their argument and discuss the exit poll that was organized in Leiden at the council elections of 21 March 2018.
