Definition and meaning of contiguity: Contiguity means the physical nearness or closeness of two or more things. In politics, contiguity is a term used to describe how two parties, ideas, or candidates are closely associated with one another, often on the same ballot or in the same political party. This is often seen as a form of strategic voting, where the voter is more likely to vote for the candidate that is associated with their party of choice. In this sense, contiguity can be seen as a way to limit choice and diversity, as it can discourage the emergence of independent candidates or ideas that don't fit in with the existing political landscape. However, it can also be seen as a way to encourage voters to think outside of the two-party system, as it gives them the opportunity to vote for candidates that are closely associated with their own values and beliefs.
