3.2.1.5 - US Elections and Candidate Selection
This lesson explains how US presidential and congressional elections work, and how candidates are selected through primaries, caucuses and national nominating conventions. It includes incumbency and campaign factors where they affect candidate selection and election chances, but leaves detailed Electoral College debate, campaign finance, direct democracy and voting behaviour to the sibling lessons in 3.2.1.5.
The US Election Map
The first AQA distinction is between an election and candidate selection.
Candidate selection
The process that chooses who appears as a party's nominee before the election; an election then chooses the office-holder.
In the USA, these two stages are especially important because parties are decentralised, states control much election administration, and candidates often need to win support in many separate contests before they reach the general election.
Three terms matter from the start:
| Term | Meaning | Why it matters |
|---|---|---|
| Legal candidate | Someone who has met campaign law and filing requirements. | FEC registration is not the same as becoming a party nominee. |
| Party nominee | The candidate officially chosen to represent a party. | Major party nominees usually emerge from primaries, caucuses and conventions. |
| Office-holder | The person elected to the office. | Winning a nomination does not guarantee winning the presidency or a seat in Congress. |
The presidency and Congress are elected in different ways.
| Election | Basic system | Main AQA point |
|---|---|---|
| President and vice president | A President serves a four-year term. Voters take part in a state-by-state general election feeding into the Electoral College. A candidate needs a majority, normally 270 of 538 electoral votes. | The election feels national, but the decisive contests are state-based. |
| House of Representatives | 435 members are elected from single-member congressional districts for two-year terms. | Representatives face frequent, localised electoral pressure. |
| Senate | Two senators per state serve six-year terms, with roughly one-third elected every two years. | Senate elections are statewide, staggered and often more expensive and visible than House races. |
The 2024 election is a useful anchor. FEC official results recorded Donald Trump and JD Vance winning 312 electoral votes, while Kamala Harris and Tim Walz won 226. The Office of the Clerk recorded the immediate post-election 119th Congress as a Republican House majority of 220 to 215 and a Senate division of 53 Republicans, 45 Democrats and 2 independents/others.
So the core teaching point is simple but powerful: US elections are not one national vote with one national rulebook. They are a federal system of elections, shaped by state law, party rules and separate presidential, House and Senate incentives.
The Presidential Cycle
The presidential election cycle takes almost two years. Candidates explore a run, raise money, build campaign organisations, enter primaries or caucuses, seek delegates, attend the party convention, campaign in the general election, and then wait for the Electoral College and congressional count to complete the constitutional process.
USAGov's official timeline gives a useful sequence:
| Stage | Typical timing | What happens |
|---|---|---|
| Early candidacy | Spring before the election year | Candidates register with the FEC once they cross the campaign finance threshold and begin building campaigns. |
| Primary debates and organisation | Summer before the election year to spring of election year | Candidates try to gain media attention, donors, endorsements and activist support. |
| Primaries and caucuses | January to June of election year | States and parties hold contests that award delegates. |
| National conventions | July to early September | Parties formally choose presidential and vice-presidential nominees. |
| General election campaign | September to early November | Nominees compete for voters, especially in competitive states. |
| Electoral College and count | December to January | Electors cast votes; Congress counts them; inauguration follows on January 20. |
The FEC threshold is worth understanding carefully. An individual running for federal office must register and file financial reports once they raise or spend more than $5,000. That makes them a regulated federal candidate, but it does not make them a nominee.
This matters for AQA because candidate selection is a filtering process. The early field may include many legal candidates. The primary and caucus season reduces that field by testing:
- money and campaign organisation
- media attention and debate performance
- issue appeal to party voters
- endorsements from party figures and interest groups
- perceived electability in the general election
- delegate arithmetic
In 2024, Donald Trump entered the Republican contest as a former president with intense name recognition and party support. Joe Biden entered the Democratic contest as the incumbent president and dominated delegate selection before withdrawing. Kamala Harris then became the Democratic nominee as sitting vice president through party delegate procedures. That makes 2024 a strong example of both the power and the limits of ordinary primary-season expectations.
Primaries And Caucuses
Primaries and caucuses are ways of selecting delegates for a party's national convention. They do not directly elect the president. They help decide which candidate will become the party nominee.
Primary
A state contest, usually by secret ballot, in which voters choose their preferred candidate and the result is used to award convention delegates.
Voters choose their preferred candidate, and the result is used to award delegates. Primaries normally allow wider participation than caucuses because voting is quicker and more familiar.
Caucus
A party meeting held at local level, such as a precinct, county or district, to select delegates.
Some caucuses use secret ballots, but others require participants to gather in candidate groups, hear speeches and try to persuade undecided participants. Caucuses can reward committed activists and strong local organisation because participation takes more time and effort.
| Feature | Primary | Caucus |
|---|---|---|
| Usual format | Secret ballot election | Party meeting |
| Organised by | State and party rules | Party organisation, sometimes with state-law links |
| Participation | Usually broader and easier | Usually smaller and more activist-heavy |
| Political skill rewarded | Mass appeal, name recognition, paid campaign operation | Organisation, enthusiasm, local persuasion |
| Democratic criticism | Still depends on state access rules and turnout | Can exclude voters who cannot attend a lengthy meeting |
Contests can also be open or closed. In an open primary or caucus, voters do not need to be registered with that party. In a closed contest, only registered party voters can take part. This affects ideological pressure. Closed contests can make candidates appeal more strongly to the party base. Open contests can pull candidates towards a wider electorate, though they can also invite strategic participation by non-party voters.
Delegate rules then convert votes into convention strength. Republican rules for the 2024 cycle required statewide presidential preference votes in primaries, caucuses or state conventions to allocate and bind delegates for at least one ballot. Contests before March 15 generally had to use proportional allocation, but Iowa, New Hampshire, South Carolina and Nevada were exempt. The rules also allowed a winner to receive all delegates above a vote threshold set no lower than 50 percent. Later contests could use other methods under party rules.
The judgement is balanced. Primaries and caucuses are more democratic than the old system of party bosses choosing nominees behind closed doors. However, they are not pure direct democracy. Turnout can be low, early states can gain huge influence, media momentum can matter as much as policy, and delegate rules can turn similar vote shares into different levels of convention power.
