A recent case out of South Carolina is drawing attention to the potential impact of open primaries on election results. South Carolina law does not require voters to formally register with a particular political party in order to cast a vote in a primary. A system in which voters can select the primary they wish to vote in regardless of party affiliation is called an open primary system. Open primary systems sometimes draw criticism because they can allow voters to engage in so-called crossover voting. Crossover voting occurs when members of one political party deliberately vote for a candidate they perceive to be weaker in an opposing party’s primary in order to give their candidate an advantage. It is important to note that voters in an open primary system do have to select only one primary in which to vote, so crossover voting naturally removes a voter’s opportunity to cast a ballot for the actual candidate of her choice in her own party’s primary. Exit polls provide evidence that voters have crossed party lines during primaries in South Carolina. For example, despite South Carolina’s traditionally conservative electorate, nearly 30% of the voters in the Republican presidential primary in 2012 were either Democrats or Independents. Further, nearly a quarter of the independents chose Ron Paul as their candidate of choice, rather than the eventual winner in the primary, Newt Gingrich.Full Article: Could Open Primaries Close the Door on Graham in 2014? : State of Elections.
