Write-in candidate

A write-in candidate is a candidate in an election whose name does not appear on the ballot, but for whom voters may vote nonetheless by writing in the person's name. The system is almost totally confined to elections in the United States. Some U.S. states and local jurisdictions allow a voter to affix a sticker, with the write-in candidate's name, to the ballot in lieu of actually writing in the candidate's name. Write-in candidacies are sometimes a result of a candidate being legally or procedurally ineligible to run under his or her own name or party; write-in candidacies may be permitted where term limits bar an incumbent candidate from being officially nominated for, or being listed on the ballot for, re-election. In some cases, write-in campaigns have been organized to support a candidate who is not personally involved in running; this may be a form of draft campaign.

Write-in candidates rarely win, and sometimes write-in votes are cast for ineligible people or fictional characters. Some jurisdictions require write-in candidates be registered as official candidates before the election. This is standard in elections with a large pool of potential candidates, as there may be multiple candidates with the same name that could be written in.

Many U.S. states and municipalities allow for write-in votes in a partisan primary election where no candidate is listed on the ballot to have the same functional effect as nominating petitions: for example, if there are no Reform Party members on the ballot for state general assembly and a candidate receives more than 200 write-in votes when the primary election is held (or the other number of signatures that were required for ballot access), the candidate will be placed on the ballot on that ballot line for the general election. In most places, this provision is in place for non-partisan elections as well.

Generally, write-in candidates can compete in any election within the United States. Typically, write-in candidates have a very small chance of winning, but there have been some strong showings by write-in candidates over the years.

In 2010, California voters passed Proposition 14 which set up a new election system for the United States Senate, United States House of Representatives, all statewide offices (governor, lieutenant governor, secretary of state, state treasurer, state controller, attorney general, insurance commissioner, and superintendent of public instruction), California Board of Equalization, and for the California State Legislature. In the system set up by Proposition 14, there are two rounds of voting, and the top two vote-getters for each race in the first round (the primary, normally held in June) advance to a second round (the general election, held in November). Proposition 14 specifically prohibits write-in candidates in the second round, and this prohibition was upheld in a court challenge. Another court challenge to the prohibition on write-in candidates in the second round was filed in July 2014.
