2020 Presidential Primaries Calendar




Each state, DC, and US territory holds a Democratic and a Republican primary, caucus, or convention to select a presidential candidate before the party nominates a candidate for a nationwide presidential election. A primary is a statewide vote in which each voter selects their preferred candidate. A caucus is a "system of local gatherings" during which voters decide on a candidate. A state convention works like the national convention, in which the jurisdictions within the state hold primaries or caucuses and then send delegates to the convention to select a candidate. Most states hold primaries. If an election is a caucus or convention, it is noted below.

While we do not usually include US territories in our state-by-state lists and people in US territories cannot vote in the presidential election, each territory does have primaries or caucuses, sends delegates to the party conventions, and is therefore included below. We have not included primaries for third parties because they do not happen consistently in every state; we have included the third party conventions when dates are available.

Five states, DC, and three territories hold Democratic and Republican conventions in different months, hence their being marked in pink on the map above: Alaska, Kansas, Kentucky, Hawaii, North Dakota, DC, Puerto Rico, Virgin Islands, and Guam.

The candidates for the Democratic and Republican parties are selected at the conventions based on the number of delegates gained from each state. Delegates are people who travel to the national conventions to represent the state. The 2020 Democratic party convention will have an estimated 3,768 pledged delegates, plus an additional 764 superdelegates. The 2020 Republican national convention will have an estimated 2,440 pledged delegates, plus an additional 110 unpledged delegates. Pledged delegates have agreed to vote for the candidate who wins the state's election. Each state has rules on how delegates are awarded to candidates. Superdelegates, or unpledged delegates, are not bound to any particular candidate and may vote however they choose. To win the party nomination, a candidate must win the majority of the party's delegates.

Each primary or caucus is open, closed, or mixed. Open means that any registered voter may vote, regardless of party registration or affiliation, but must choose only one party's ballot to vote on. Closed means that only voters registered with the particular party may vote, and, in most cases, voters must be registered with the party before voting day. Mixed most often means that independent voters may vote without declaring party affiliation, though the rules vary state-by-state and by party.

Some state Republican parties have canceled their Republican primaries, including South Carolina, Kansas, and Arizona. According to Nik DeCosta-Kilpa, the cancelations have precedent in both parties: "[T]here's also a history of parties of an incumbent president canceling primaries in those states to save money, since the parties pay for primary elections. But when it has happened, it has usually been the case that the president was running without any major primary challengers. Arizona Democrats didn’t hold a presidential primary in 2012 and 1996. Kansas did the same in 1996, citing $1.4 million in savings. And both parties in South Carolina have canceled primaries twice since the 1980s." The canceled primaries are still listed below but marked as canceled.
