The sample in public opinion surveys must be representative of the whole population, meaning that the views of those in the sample accurately and proportionately reflect the views of the whole population. The size of the sample can vary depending on the specific survey, but it does not need to be a certain percentage of the targeted population. Additionally, it does not necessarily have to include all registered voters, as some surveys may focus on specific demographics or subsets of the population.
