WHICH PRIMARY SHOULD WE CONDUCT?

Which is the best primary for us - closed, semi-closed, open, semi-open or run-off. Here are their definitions:*

• Closed. People may vote in a party's primary only if they are registered members of that party. Independents cannot participate. Note that because some political parties name themselves independent, the term "non-partisan" often replaces "independent" when referring to those who are not affiliated with a political party.
• Semi-closed. As in closed primaries, registered party members can vote only in their own party's primary. Semi-closed systems, however, allow unaffiliated voters to participate as well. Depending on the state, independents either make their choice of party primary privately, inside the voting booth, or publicly, by registering with any party on Election Day.
• Open. A registered voter may vote in any party primary regardless of his own party affiliation. When voters do not register with a party before the primary, it is called a pick-a-party primary because the voter can select which party's primary he or she wishes to vote in on election day. Because of the open nature of this system, a practice known as raiding may occur. Raiding consists of voters of one party crossing over and voting in the primary of another party, effectively allowing a party to help choose its opposition's candidate. The theory is that opposing party members vote for the weakest candidate of the opposite party in order to give their own party the advantage in the general election. An example of this can be seen in the 1998 Vermont senatorial primary with the election of Fred Tuttle for the Republican candidate.
• Semi-open. A registered voter must not publicly declare which political party's primary that they will vote in before entering the voting booth. When a voter identifies their self to the election officials, they must request a party's specific ballot. Only one ballot is cast by the voter. In many states with semi-open primaries, election officials or poll workers from their respective parties record each voter's choice of party and provide access to this information. The primary difference between a semi-open and open primary system is the use of a party-specific ballot. In a semi-open primary, a public declaration in front of the election judges is made and a party-specific ballot given to the voter to cast. Certain states that use the open-primary format may print a single ballot and the voter must choose on the ballot itself which political party's candidates they will select for a contested office.
• Run-off. A primary in which the ballot is not restricted to one party and the top two candidates advance to the general election regardless of party affiliation. (A run-off differs from a primary in that a second round is only needed if no candidate attains a majority in the first round.)
There are also mixed systems in use. In West Virginia, Republican primaries are open to independents, while Democratic primaries were closed. However, as of April 1, 2007, West Virginia's Democratic Party opened its voting to allow "individuals who are not affiliated with any existing recognized party to participate in the election process".
