what is split ticket voting?

Split-ticket voting can be used as a form of tactical voting in countries (such as the United States) dominated by two parties where a voter is not a wholehearted supporter of either party. It can also be used in countries (such as Germany) which use a variety of voting systems. For example, a voter supporting a smaller party could vote for that party in an election held on the proportional representation system but vote for a larger party when an election is being held on a first past the post basis.
