¶ Election and Political Terms
- AVEV - Absentee Vote Early Vote - Refers to the multiple ways someone can vote prior to election day.
- AVR - Automatic Voter Registration - Policy/process where eligible voters are placed on the voter rolls automatically usually when they interact with a state agency such as the DMV
- BOE - Board of Elections - Entity that administers elections, at the state and/or county level

- EDay - Election Day
- IPEV - In Person Early Vote - The process of voting whereby a voter goes to a polling location before election day and casts their ballot.
- Midterm Election or Midterms - Type of election where the people can elect their representatives in the middle of the term of the executive or of another set of members. Or the Election that occurs in the middle of a presidential election. For example, the last two Presidential elections occurred in 2012 and 2016. The Midterm elections were in 2014 and 2018 because the president was not up for re-election those years. Traditionally, voter turnout is lower during midterms elections.
- Party reg - party registration - Political party a person is registered with on their voter registration form (for states that collect that information)
- PEVL - Permanent Early Voting List - Option some states offer that allows voters to automatically receive a mail ballot each election
- Primary Election (Open or Closed) - An election held to determine which of a party's candidates will receive that party's nomination and be their sole candidate later in the general election. In an open primary, all voters can vote for any candidate they prefer, regardless of the voter’s or candidate's party affiliation. In a closed primary, voters can only vote for a candidate from the party that the voter belongs to.
- SoS - Secretary of State - Entity that administers elections in some states
- VBM - Vote by Mail - The process by which a voter casts their vote by mailing the ballot to the county election official.
- VRA - Voting Rights Act - Passed in 1965 and meant to protect voting rights and end discrimination. Required certain jurisdictions.
- Attempts - An effort to contact an individual voter directly. Usually used when discussing a field program referencing doors knocking, phone calls and text messages. Attempts are recorded in VAN as a canvass status.
- Base / base voters - Voters who are thought will always turn out for a specific party
- Canvassing - An effort to contact and speak directly to a list of targeted voters. Usually refers to knocking on their door, but can also be event-based.
- Constituency - A body of voters in a specified area who elect a representative to a legislative body.
- Contacts - Refers to an interaction between a campaign representative and a voter where information was gathered about the voter (usually at the door or on the phone). Often used interchangeably with “conversation” or “touch.” Broadly represented in VAN as the Canvass Status simply called "Canvassed".
- Day of Action - A day on the campaign during which volunteers are organized to take collective action (such as house meetings, canvasses, phone banks, text banks) en masse across the district, state, or Country.
- Direct mail - One element of paid communications, a direct or paid mail program is made up of individual mail pieces sent directly from your campaign to a targeted list of voters
- Direct Voter Contact - Attempts by the campaign to directly reach or engage voters. Tactics include face-to-face conversations (usually at the door), phone conversations, text messaging, and mail. This is in contrast with other voter contact methods such as Direct Mail or Paid Media.
- Distributed Organizing - Organizing model that prioritizes the work being done by chapters or organization subsets and focuses on how building momentum at the local level can help yield larger victories
- Dry Run - A scheduled GOTV practice, usually in the last weeks leading up to the election, where reporting systems, Staging Locations, and volunteer leadership are tested
- Earned Media - Getting news coverage using only PR tactics/buzz/events. Free media or press that is “earned” by the campaign, rather than paid advertising. For example, campaigns may choose to put together events in order to attract press who will cover a particular story or narrative.
- Field - Referring to “boots on the ground,” i.e. canvassers, door knocks, phone calling, texting and other Direct Voter Contact methods. Can also include other volunteer or organizer-led activism and engagement, like letters to the editor or postcard writing.
- Flake Rate - The percent of people who sign up to volunteer for a campaign or event but do not participate.
- GOTV - “Get Out The Vote” - Any program related to getting people to vote in an election. The final weeks or days of the campaign in which the entire focus of the campaign is turning out supporters to vote for the candidate. Commonly used as a verb. Pronounced "G. O. T. V." and not "Go TV".
- GOTV Universe - List of voters your campaign has targeted for engagement during GOTV. It will include your identified supporters, as well as those with relatively high support but relatively low turnout propensity.
- ID - A vote intention from a specific voter given to the campaign, usually in a canvass or a survey context. Can also be used as a verb. Usually recorded as 1 - Strong Support; 2 - Lean Support; 3 - Undecided; 4 - Lean Oppose; 5 - Strong Oppose.
- Intersectionality - First coined in 1989 by American civil rights advocate and leading scholar of critical race theory, Columbia and UCLA law professor Kimberlé Williams Crenshaw, which is the study of overlapping or intersecting social identities and related systems of oppression, domination, or discrimination. Put more simply, it is about constituent groups that are part of larger advocacy group that feel that they are invisible, not included and erased from the discussions, concerns, and advocacy of the main group that claims to also represent their interest. For example, women of color issues about racism not being defended among mainstream feminist groups; violence against LGBTQ people of color not recognized among mainstream Gay Rights groups; the needs of girls not considered in policy discussions about the school-to-prison pipeline that often focuses on boys, etc.
- Neighborhood Team Leader - In the Team model of organizing this person is a committed volunteer who is empowered to run the campaign’s direct voter contact operations in their neighborhood. This person usually manages other volunteer leaders,such as Canvass Captains, Phone Bank Captains, and Data Captains.
- Paid media - Buying political ads (newspaper, TV, etc) with campaign money
- Path to Victory - Calculation of the campaign’s vote goal (also called the win number), and how many voters must be persuaded, registered, and/or turned out to reach that vote goal. A sophisticated pathway to victory will also include an analysis of who the target voters are for persuasion, registration, and turnout.
- Penetration - Percentage of a voter universe/list that has been contacted by the campaign. For example, one might say that we’ve reached 70% penetration, to indicate that we have had conversations with 70% of the voters the campaign is targeting. Often mistakenly used interchangeably with “saturation” which refers to how many times each voter is contacted.
- Persuasion - Targeting undecided voters and persuading them to vote for you in the election, essentially moving them from undecided to decided
- Persuadable voters - Voters that the campaign will target and attempt to persuade to vote for the candidate. Typically, refers to voters who are somewhat likely to turn out to vote but are currently undecided or do not have a strong partisan identity.
- Predictive dialer - Software that automatically dials through a phone list, connecting only with live callers (skipping answering machines, busy signals, and disconnected numbers), used to accelerate passes through a phone universe. Rates for this service vary, and some training of volunteers is required before use. The average dialer will triple your contact rates.
- Relational Organizing - Utilizes a volunteer’s or organizer’s existing relationships to build power for an organization. Relational organizing tools let a campaign distribute calls to action, capture data, and track metrics on their relational organizing program
- Shift - Amount of time a volunteer should commit to volunteering when they sign up. During GOTV, typically 3-4 hours in length. Notably, this is different than the number of volunteers recruited, as volunteers can (and should!) complete multiple shifts. Because measuring shifts is how capacity is calculated, this term will be used frequently in a variety of ways.
- Snowflake model - Distributed leadership model used to organize communities in labor movements, advocacy efforts, and electoral campaigns. Adopted as “The Neighborhood Team Model” on President Obama’s campaign in 2008, with the help of organizer Marshall Ganz, and has been used widely by Democratic campaigns since. Called the “Snowflake Model” because when you draw it as an organizational chart, it looks like a snowflake. The model’s success depends on empowering and training volunteers to take on leadership roles so that they might be multipliers for the campaign.

- Sporadic voters - People who are registered to vote but only occasionally turn out to vote; sometimes used interchangeably with the term “drop-off voters”—people who tend to vote in Presidential elections but not in Midterm or local elections.
- Staging location - A place where people will gather before and after the canvass. Can be a private home, park, school, or any other location that will accommodate your group and allow for a brief training.
- Surrogate - Person who acts on the behalf of a candidate running for some sort of political office. Often appears at public events that the candidate cannot make it to, or may simply appear to bolster the image of the candidate in a certain demographic. An influential or well-known person—often an elected official, celebrity, or local civic leader are examples of a surrogate.
- Swing voter - Unlike base voters, swing voters will not be loyal to a candidate just based off of party lines. They could vote Republican or Democrat. These voters are important during any campaign because they can make or break meeting your voter goal and win the election. Swing voters have twice the impact as Turnout voters on the election outcome because switching support for a candidate both removes a vote from your opponent and adds a vote to your candidate.
- Targeting - Selection of voters whom the campaign will directly engage in order to register, persuade, and/or turn out to vote. Campaigns rarely have the capacity and resources to engage all voters, so they have to select a smaller number of voters whose support they believe they can garner through interventions such as direct voter contact or paid media.
- TCPA - Telephone Consumer Protection Act - Federal statute enacted in 1991 designed to safeguard consumer privacy. This legislation restricts telemarketing communications via voice calls, SMS texts, and fax. Vendors have formed a trade association, the P2P Alliance, that petitioned the FCC in May 2018 to clarify the TCPA's legality.
- Organizing Turf - Geographic area assigned to an organizer or volunteer containing a list of people for them to engage (i.e., the area of their walk packet). To “cut turf” means to determine the boundaries of each individual’s assignment. Sometimes, one refers to an organizer’s turf as the region in which they organize. Other times, someone might refer to a turf and simply mean a canvass packet (also called a walk list).
- Turnout - Voters showing up to cast their ballots. For example, if one says “turnout is high,” they mean that a high number of registered voters have cast their ballots (in person and/or by mail).
- Universe - List of voters the campaign has targeted for engagement. The campaign has a universe for direct voter contact (door, phone, text conversations, mail), and also for paid media (TV, digital ads).
- VAN - Voter Activation Network - Company that powers Votebuilder, an online CRM (Customer Relationship Manager) tool that Democratic Parties and candidates around the country use to organize for the election of candidates at all levels of government. VAN was founded in 2001 and has since grown to be the most widely used organizing tool for field campaigns use by Democrats.
- Vote goal - Number of votes you need to win your election. With this goal in place, you know how many voters you need to convince to turn out to the polls in order to win the election. By consulting the local board of elections you can see the history of voter turnout in your area and the number of registered voters then quantify what your voter goal should be.
- VPB - Virtual phone bank - Online call tool arranged by the campaign so that volunteers can call and speak to their targets from anywhere. Most often this is arranged through VAN, so that a script is provided, and data is entered immediately by the caller.
- Walk list/packet - List of addresses (usually of voters) given to a canvasser to knock doors and deliver a script or have a specific conversation

- PAC - Political Action Committee - Organization formed to promote its members' views on selected issues, usually by raising money that is used to fund candidates who support the group's position. PACs monitor candidates' voting records and question them on their beliefs on issues of interest to their membership.

Therefore, for example, even if a candidate is losing on an issue according to a certain poll of likely or registered voters, if the percentage point differences are close, that margin of error could provide comfort to the candidate with the lower percentage that they may still be within a position to overtake the lead.
- Multi-modal - Running a survey with multiple modes such as phone, online, SMS, etc.
