How NDTC Prepares Democratic Candidates for Every Type of Election

Most first-time candidates come into their campaigns focused on the right things: their message, their community, their vision for what they want to change. What catches some candidates off guard is the infrastructure around the election itself. Specifically, the fact that not all elections work the same way.

The types of elections you'll encounter as a Democratic candidate or campaign staffer each operate on different timelines, draw different electorates, and require different strategies to win. Treating a primary election the same as a general election is one of the most common and costly mistakes a first-time candidate can make. Treating a special election like a normal race on a normal timeline is another.

This guide breaks down the three main types of elections — primary, general, and special — so that you and your team understand exactly what you're getting into and how to prepare accordingly.

Why Understanding the Types of Elections Matters for Your Campaign

The type of election you're running in determines nearly everything about your campaign strategy.

Who turns out to vote? How big is your target universe? What are the filing deadlines and ballot access rules? What kind of message cuts through? How long do you have to build an operation? The answers to all of those questions change depending on which type of election you're in.

Campaign staff in particular need a clear handle on this. A field director who understands the turnout dynamics of a primary election versus a general election will build the right voter contact universes. A finance director who accounts for a shortened special election timeline will set a better fundraising cadence. Getting this right is foundational, and it's exactly the kind of operational knowledge that separates prepared candidates right out of the gate.

Primary Elections: Where Your Democratic Campaign Begins

For most Democratic candidates, the journey to a general election starts with a primary election. A primary is the election within a party that determines who will go on to represent that party on the general election ballot.

Understanding primary elections means understanding their defining characteristic: the electorate is much smaller and much more engaged than in a general election. Only registered party members (or, in some states, registered independents) can participate, and the people who actually show up to vote in primaries tend to be the most politically active members of the community. Turnout can be dramatically lower than in a general election, which means every vote is proportionally more powerful.

What does this mean for your campaign strategy? Your voter universe shrinks dramatically. In a primary election, you're not talking to every registered voter. You're talking to a much narrower slice of high-propensity Democratic primary voters. Your voter file targeting needs to reflect that, and your canvassing and phone banking scripts need to speak to a more politically engaged audience.

Party relationships matter more. Primary voters pay attention to endorsements from local Democratic clubs, unions, and elected officials in ways that general election voters often don't. Building those relationships early is an investment in primary viability.

The message is different. In a primary election, you're making the case that you're the strongest Democrat in the race, best positioned to carry the party's values and win in November. In a general election, you're making the case to a much wider audience that includes persuadable independents. Conflating these two audiences is a trap.

Also worth knowing is that some states and jurisdictions have nonpartisan primaries, sometimes called "jungle primaries," where all candidates from all parties appear on the same ballot and the top finishers advance to the general election, regardless of party. If your race uses this format, your strategy will look significantly different from a traditional party primary.

General Elections: The Main Event

If the primary election is where you earn your place on the ballot, the general election is where you earn the office. General elections are open to all registered voters, which means the electorate expands dramatically, and the range of voters you need to reach expands with it.

General elections are what most people picture when they think about campaigns: high turnout (particularly in presidential and midterm cycles), robust paid media, broad voter contact programs, and the full force of party infrastructure behind competitive candidates.

Key distinctions your campaign needs to plan for:

Turnout is higher, sometimes dramatically. The universe of voters who participate in a general election is far larger than in a primary election. Your field program needs to scale accordingly, and your targeting needs to expand beyond base Democrats to include persuadable independents and low-propensity voters who may not have shown up in the primary election.
The message broadens. General election messaging is about coalition-building. You're not speaking just to committed Democrats, you're speaking to everyone in your district who might be convinced that you're the right person for the job. Message discipline and broad appeal matter more than ever.
Party and outside support kick in. Competitive general elections attract investment from state and national Democratic committees, labor unions, and aligned advocacy organizations. Understanding how to coordinate with those entities and how to position your campaign to attract that support is a key general election skill.
Timing shifts. General elections in midterm years fall in November, but down-ballot general elections sometimes happen at other times of year, depending on the state and office. Know your specific election calendar well in advance.

Special Elections: High-Stakes, Short Timelines, and Small Margins for Error

Special elections are the wildcard of the types of elections a Democratic candidate might face. They're called to fill a seat that has become vacant between regular election cycles, either due to a resignation, a death in office, an appointment to another position, or another reason — and they operate on an entirely different set of rules from a normal primary or general.

The defining challenge of a special election is time. While a typical campaign has months to build a voter contact program, raise money, and establish name recognition, special elections often compress all of that into a matter of weeks. Filing deadlines can come fast, and the period between announcement and Election Day can be shorter than the timeline of a normal primary alone.

What makes special elections strategically distinct:

The electorate is unpredictable. Special elections don't fall on normal Election Day cycles, which means turnout patterns are harder to model. Fewer voters show up overall, and the composition of who turns out can shift in ways that normal voter file data doesn't always capture. Campaigns need to be nimble.
Base mobilization becomes the priority. When the universe of voters is uncertain and the timeline is short, the most reliable strategy is usually to focus on mobilizing your known base rather than devoting limited time to broader persuasion. Special elections are often won by the campaign that gets its people to the polls most effectively, not by the one with the most persuasive message.
Name recognition must be built fast. Candidates in special elections sometimes have no existing name recognition in the district and must introduce themselves to voters in a fraction of the normal time. Earned media, community events, and high-volume voter contact are all critical from day one.
The rules may be different. Special elections don't always follow the same ballot access and filing processes as regular elections. Some states have unique rules that govern how candidates qualify in a special election. Research your state's requirements the moment a special election is called.

How the Type of Election Should Shape Your Strategy

Here's the simple version, for candidates and campaign staff who need a working framework:

In a primary election, your job is to mobilize your base of engaged Democratic voters, earn party endorsements, and make a compelling case for why you're the strongest Democratic candidate in the race.

In a general election, your job is to expand your coalition beyond the base, persuade independents, and run a high-volume voter contact operation at a scale that matches the larger electorate.

In a special election, your job is to move fast, focus on base mobilization, and build a compressed but complete campaign operation on a timeline that would feel impossible in any other context.

Like all campaign skills, understanding the nuances of different types of elections is learned with practice. The campaigns that get it right are the ones whose candidates and staff come in prepared.
