In nonpartisan elections, each candidate for office is eligible based on her or his own merits rather than as a member of a political party. No political affiliation (if one exists) is shown on the ballot next to a candidate. Generally, the winner is chosen from a runoff election where the candidates are the top two vote-getters from a primary election. In some elections, the candidates might be members of a national party, but do not run as party members for local office.
Louisiana uses a nonpartisan blanket primary, also called a “jungle primary”, for state and local offices. In this system, all candidates run against each other regardless of party affiliation during the primary, and then the two most popular candidates run against each other even if they are members of the same party. This form of runoff election weakens political parties and transforms a partisan election into a partly nonpartisan election. Nebraska uses a single nonpartisan primary for the State Legislature but not for other state and local races.
Nonpartisan elections are generally held for municipal and county offices, especially school board, and are also common in the election of judges. In some nonpartisan elections, it is common knowledge which candidates are members of and backed by which parties; in others, parties are almost wholly uninvolved and voters make choices with little or no regard to partisan considerations.
While nonpartisan democracies can allow for a wide selection of candidates (especially within a no-nomination system whereby voters can choose any non-restricted person in their area), such systems are not incompatible with indirect elections (such as for large geographical areas), whereby delegates may be chosen who in turn elect the representatives.
Even if a government’s executive officer or legislature is partisan, appointments of cabinet members, judges, or directors of government agencies, may be nonpartisan. The intent of appointing government officials in a nonpartisan manner is to insure the officers can perform their duties free from partisan politics, and are chosen in a fair manner that does not adversely affect a political party. Twelve US states use the Missouri Plan, and two use a variation of it, to choose judges in a nonpartisan manner. Several countries with partisan parliaments use nonpartisan appointments to choose presidents.
In nonpartisan legislatures, there are no typically formal party alignments within the legislature; even if there are caucuses for specific issues. Alliances and causes with a nonpartisan body are often temporary and fluid since legislators who oppose each other on some issues may agree on other issues. Despite being nonpartisan, legislators typically have consistent and identifiable voting patterns. Decisions to investigate and enforce ethics violations by government officials are generally done on the basis of evidence instead of party affiliation. Committee chairs and other leaders within the legislature are often chosen for seniority and expertise, unlike the leaders in a partisan legislature who are often chosen because of loyalty to a party.
