Quiz: Remember the definition of mal de mer?
A vote for candidates of different political parties on the same ballot, instead of for candidates of only one party. In the presidential elections, for example, a voter may choose a Republican candidate for president, but a Democratic candidate for senator. Split-ticket voting is not allowed in primaries (see closed primary, direct primary, open primary). The increasing occurrence of split-ticket voting reflects support of individual candidates rather than unswerving party loyalty.
