During elections, political polls provide critical data for the support each candidate receives. For that reason, the measurement of questions asking about candidate support has been receiving some research attention. As the online survey is increasingly becoming a widely used tool for public opinion and election polls, evaluation of the measurement error associated with this survey mode is of importance. This study examines whether a candidate name order effect exists in presidential primary election surveys in the US. The findings show that contrary to previous studies the order of names does not have a significant impact on the support candidates received.
