With a record 42% of U.S. voters self-identifying as independent, there is increasing demand for non-partisan politics. Open primaries allows millions of voters to have access to the first and critical round of elections, cutting into partisan control of the electoral process (where the parties determine not only the issues that get discussed, but how they are discussed, as well as who wins the elections and the legislation that gets passed).

A:California and Washington use the Top Two primaries system for all state and federal elections.

Closed: Independents cannot vote in a party primary, unless party votes to open it for a specific election.
Open: There is no partisan voter registration. Voters must choose a party primary in which to vote.
Semi-Closed: Independents or unaffiliated voters can vote in a party primary. However, they must reregister into a party on that day. Some states require a waiting period to reregister such as CO and ME. Other states such as NH and RI allow you to reregister at the poll. Parties can elect to bar independents from participating.
Semi-Open: Independents or unaffiliated voters can vote in state primary. They must ask for a party ballot, and can only vote in that party primary. Parties can elect to bar independents from participating.

The parties are private organizations and are free to do that however they choose and with their own, not the taxpayers, funds.
