Primary elections allow voters to determine which candidates compete in the general election and can be nonpartisan or partisan. In partisan primaries, voters choose the candidates they prefer for a political party to nominate in the general election.
The laws governing primary elections vary from state to state and can even vary within states by locality and political party. For example, only registered party members are allowed to vote in closed primaries, while registered party members and unaffiliated voters are allowed to vote in semi-closed primaries, and all voters are allowed to vote in open primaries.
Primary elections also vary by the way their outcomes are determined. Majority systems require the winning candidate to receive at least fifty percent of the votes cast, while plurality systems do not. In top-two primaries, top-four primaries, and blanket primaries, all candidates are listed on the same ballot, regardless of partisan affiliation.

Background
In general, there are two broad criteria by which primary elections can vary from jurisdiction to jurisdiction:
1. Rules of participation: In jurisdictions that conduct partisan primaries, who can vote in a party's primary? Is participation limited to registered party members, or can other eligible voters (such as unaffiliated voters or voters belonging to other parties) participate? In general, there are three basic types of primary election participation models: open primaries, closed primaries, and semi-closed primaries. Several states also use a top-two primary or a variant of that system.
- In closed primaries only registered party members are allowed to vote.
- In semi-closed primaries, registered party members and unaffiliated voters are allowed to vote.
- In open primaries, all voters are allowed to vote.
- In top-two primaries, top-four primaries, and blanket primaries, all candidates are listed on the same ballot, regardless of partisan affiliation and voters may vote for candidates from more than one party.
2. Vote requirements: What share of the total votes cast does a candidate have to receive in order to advance to the general election? Methods for determining primary election outcomes include plurality voting systems ans majority voting systems. Two states, California and Washington, use top-two primaries, while one, Alaska, uses a top-four primary. Both are plurality systems. Maine use ranked-choice voting for some primaries, which is a majority system.
Primary election systems used in Connecticut
Congressional and state-level elections
In 23 states, at least one political party utilizes closed primaries to nominate partisan candidates for congressional and state-level (e.g. state legislators, governors, etc.) offices. In 19 states, at least one party utilizes open primaries to nominate partisan candidates for these offices. In 12 states, at least one party utilizes semi-closed primaries. In 5 states, top-two primaries or a variation are used.[1] These state primaries are a separate entity and are not included in the totals for open, closed, or semi-closed primaries.
Connecticut law says: "No person shall be permitted to vote at a primary of a party unless (1) he is on the last-completed enrollment list of such party in the municipality or voting district, as the case may be, or (2) if authorized by the state rules of such party filed pursuant to section 9-374, he is an unaffiliated elector in the municipality or voting district, as the case may be, provided if two or more such parties are holding primaries on the same day in such municipality or voting district, whether for the same offices or different offices, such unaffiliated elector may vote in the primary of only one such party. Such state party rules may authorize unaffiliated electors to vote for some or all offices to be contested at its primaries."[2]
Winners in primary elections are determined via plurality vote, meaning that the candidate with the greatest number of votes wins the election even if they did not win an outright majority of votes cast.[3]

Footnotes
- ↑ Top-two primary systems, such as those utilized in California, Nebraska, and Washington, and variations of those systems, such as the top-four system used in Alaska and the majority-vote system used in Louisiana, are sometimes classified as open primary systems because voter participation in such primaries is not tied to partisan affiliation. For the purposes of this article, these primaries are considered to be a separate entity. For more information about top-two primaries and their variations, see this article.
