The internet has global coverage, so, although many South Africans are likely to be included in the poll because News24 is a SA news network, people of other nationalities could be included, unless the poll itself expressly excludes them, and does so in a robust, reliable way, so as to eliminate misuse or abuse of the poll. Another factor is accessibility. An online poll requires internet access, so not all South Africans wishing to participate may be able to do so. Another factor may be multiple accounting in which the same person could register in the poll several times. More needs to be known about the purpose of the poll and what measures are being employed to give it validity. A poll can be indicative rather than definitive.
