Why do people vote for Hillary Clinton rather than Donald Trump? One of the most important reasons why people choose candidates and political parties is based on their positions on various political issues. Voters in general seek to choose the candidate which is the closest match to their own political attitudes. Stig Hebbelstrup Rye Rasmussen writes that not all voters perform this task equally well, and that one of the most important factors, and so far overlooked, is the role intelligence plays in determining which party best matches the political attitudes of the individual voter.
