<P> In the United States, other types can be differentiated: </P> <Ul> <Li> Closed primary . People may vote in a party's primary only if they are registered members of that party prior to election day . Independents cannot participate . Note that because some political parties name themselves independent, the terms "non-partisan" or "unaffiliated" often replace "independent" when referring to those who are not affiliated with a political party . Eleven states--Delaware, Florida, Kansas, Kentucky, Maine, Maryland, District of Columbia, Nebraska, New Mexico, New York, Pennsylvania, and Wyoming--have closed primaries . </Li> <Li> 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 . Thirteen states--Alaska, Arizona, Colorado, Iowa, Kansas, Massachusetts, New Hampshire, New Jersey, North Carolina, Oregon, Rhode Island, Utah, and West Virginia--have semi-closed primaries that allow voters to register or change party preference on election day . </Li> <Li> Open primary . A registered voter may vote in any party primary regardless of his or her own party affiliation . Eleven states - Alabama, Arkansas, Georgia, Hawaii, Michigan, Minnesota, Missouri, Montana, North Dakota, Vermont, and Wisconsin - have open primaries . 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 nomination of Fred Tuttle as the Republican candidate in the general election . </Li> <Li> Semi-open . A registered voter need not publicly declare which political party's primary that they will vote in before entering the voting booth . When voters identify themselves to the election officials, they must request a party's specific ballot . Only one ballot is cast by each 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 . </Li> <Li> Blanket primary . A primary in which the ballot is not restricted to candidates from one party . </Li> <Li> Nonpartisan blanket primary . A primary in which the ballot is not restricted to candidates from one party, where the top two candidates advance to the general election regardless of party affiliation . Louisiana has famously operated under this system, which has been nicknamed the "jungle primary ." California has used a nonpartisan blanket primary since 2012 after passing Proposition 14 in 2010, and the state of Washington has used a nonpartisan blanket primary since 2008 . </Li> </Ul> <Li> Closed primary . People may vote in a party's primary only if they are registered members of that party prior to election day . Independents cannot participate .
