The US Electoral System (AQA A-Level Politics): Revision Notes
The US Electoral System
Types of elections in the USA
The United States conducts four main types of elections, each serving a different purpose in the democratic process.
Presidential elections use an indirect system called the Electoral College to choose the president every four years. Rather than directly electing the president through a national popular vote, voters in each state select electors who then formally elect the president.
Congressional elections directly elect members of both chambers of Congress. The entire House of Representatives and one-third of the Senate face election every two years. Elections held between presidential elections are known as midterms.
Primaries are formal secret ballot elections used to select party candidates. These are most important for choosing presidential candidates, but they also determine candidates for congressional and state elections. Some states still use caucuses, though these are increasingly rare.
Direct democracy includes various methods of citizen participation such as ballot initiatives, referendums and recall elections at state level.
Understanding Election Types:
The four main types serve distinct purposes:
- Presidential - Indirect election through Electoral College for executive leadership
- Congressional - Direct election for legislative representation
- Primaries - Party candidate selection process
- Direct democracy - Citizens directly voting on policy questions
Electoral timings
The Constitution establishes clear timings for major federal elections, demonstrating the rigidity of the US constitutional system.
Presidential elections occur every four years in November, with the formal inauguration taking place the following January. If a president dies or resigns during their term (as Richard Nixon did in 1974), the vice president assumes the presidency and completes the remainder of the term without triggering a new election.
Congressional elections take place every two years. The entire House of Representatives (435 members) and approximately one-third of the Senate (around 33-34 senators) face election at this time. Those elections occurring between presidential contests are called midterms.
Midterm Elections:
Midterm elections occur halfway through a president's four-year term and are crucial for maintaining congressional accountability. They allow voters to respond to the president's performance and can shift the balance of power in Congress, potentially creating divided government.
Individual states determine the timing of other elections, including state, local and primary elections. This means voters in many states cast ballots once or twice annually. For example, Wisconsin held primary and local elections in April 2020 (controversially during the COVID-19 pandemic), then voted again in November 2020 for the presidential election and congressional seats.
The federal structure and state control
Many aspects of electoral administration operate at state level rather than being controlled by the federal government. This reflects the federal nature of American government and provides an important example of state sovereignty.
Federal rules establish broad frameworks, such as:
- Requirements that polling stations be accessible to people with disabilities
- Prohibition of racial or gender-based voting discrimination
- Constitutional provisions for election timings
Beyond these basics, states possess considerable autonomy in electoral matters.
Voter registration requirements vary significantly between states. North Dakota, for example, has no formal voter registration system at all, though voters must produce identification when voting. Other states have much stricter registration requirements.
Ballot access laws also differ across states, affecting which candidates appear on ballot papers. Tight regulations in some states meant that in 2020, Green Party candidate Howie Hawkins did not appear on the ballot in 21 states. In 17 of these he was a write-in candidate (voters could manually write his name on the ballot), whilst in four states there was no opportunity to vote Green at all.
Gerrymandering: A Key Concept
Gerrymandering is the deliberate manipulation of electoral district boundaries for party advantage at elections. This controversial practice demonstrates how state control can be used to gain political advantage.
Recent examples include North Carolina and Maryland, where state legislatures have redrawn House district boundaries in ways that favour the dominant party. Gerrymandering typically occurs after the ten-yearly national census when districts are reapportioned due to population changes.
Important: Gerrymandering only applies to House of Representatives elections, as Senate elections use the entire state as the constituency.
States also control how primaries are organised. Although parties have input in determining procedures for awarding delegates to the national nominating convention (the occasion when the successful candidate is formally endorsed as their party's presidential candidate), state authorities actually conduct the elections.
In summary, although national elections take place, there is no truly national system of elections in the United States. This reflects the federal structure where states retain significant sovereignty in electoral matters.
The majoritarian electoral system
Nearly all US elections employ a majoritarian electoral system where the candidate receiving the most votes wins. This is the standard "first-past-the-post" or "winner-takes-all" approach used for most congressional elections.
However, important exceptions exist because electoral systems are determined at state level with no federal requirements (except for the Electoral College).
State-Level Electoral Variations:
Three notable exceptions demonstrate state autonomy in electoral design:
Georgia's top-two system requires Senate candidates to secure over 50% of the vote. If no candidate achieves this threshold, a runoff election occurs eight weeks later between the top two candidates. This happened in January 2021 when both of Georgia's Senate seats went to runoff elections, as no candidates secured over 50% in November 2020.
California's non-partisan blanket primary means the top two candidates from the primary election proceed to the general election, regardless of party affiliation. In 2018, as California is heavily Democratic, two Democrats topped the primary and therefore contested the November Senate election. California Republicans had no candidate on the ballot.
Maine's ranked-choice voting system, introduced in 2018, operates similarly to single transferable vote (STV) for congressional and local elections. Voters rank candidates in order of preference, and if no candidate wins a majority of first-preference votes, the lowest-placed candidates are eliminated and their votes redistributed according to second preferences.
Worked Example: Maine's Ranked-Choice Voting
The 2018 midterms in Maine's 2nd congressional district demonstrate how ranked-choice voting works:
Step 1: Initial count of first-preference votes
- No candidate achieved over 50% of first-preference votes
Step 2: Elimination and redistribution
- The lowest-placed candidates were eliminated
- Their votes were redistributed according to voters' second preferences
Step 3: Final result
- The eventual winner did not receive the most first-preference votes
- They won only after the redistribution of preferences
This demonstrates how ranked-choice voting can produce different results than traditional majoritarian systems.
The Electoral College system
Presidential elections use an indirect method through the Electoral College rather than a direct national popular vote. This system reflects the federal structure of the United States and is unique to presidential elections.
Each state (plus Washington DC) receives an allocation of Electoral College votes (ECVs) equivalent to the size of their congressional delegation.
Electoral College Vote Formula:
The number of ECVs for each state is calculated as:
Key implications:
- Every state has a minimum of 3 ECVs (reflecting two senators and at least one House member)
- California has the most ECVs (55), equating to its two senators and 53 House members
- Washington DC has no voting members of Congress but the Twenty-first Amendment (1961) granted it 3 ECVs
Worked Example: Calculating Electoral College Votes
Let's calculate the ECVs for different states:
California (most populous state):
- Senators: 2
- House members: 53
- Total ECVs: ECVs
Wyoming (least populous state):
- Senators: 2
- House members: 1
- Total ECVs: ECVs
Texas (after 2010 census):
- Senators: 2
- House members: 36
- Total ECVs: ECVs
This shows how population directly affects Electoral College representation, though smaller states receive proportionally more influence due to the guaranteed minimum of 3 ECVs.
The allocation of Electoral College votes undergoes recalculation every ten years following the national census through a process called reapportionment. States experiencing above-average population growth gain both ECVs and House districts, whilst those with declining populations lose them. After the 2010 census, Texas gained four ECVs for the 2012 election, whilst Ohio and New York each lost two.
The debate over whether the Electoral College serves American democracy effectively continues to generate significant controversy.
Evaluation of the US electoral system
The US electoral system demonstrates both considerable strengths and significant weaknesses.
Strengths
The frequency and number of elections provides extensive opportunities for political participation. Citizens regularly vote for positions at federal, state and local levels, ensuring democratic accountability across multiple layers of government.
The majoritarian system typically delivers clear results and single-party control of legislative chambers. This can facilitate effective governance and makes accountability easier as voters know which party is responsible for legislative outcomes.
Federal structure is reinforced by allowing individual states significant discretion over electoral administration. This respects state sovereignty whilst operating within a broad national framework to prevent discrimination.
Primaries and caucuses enable ordinary voters to play the decisive role in selecting party candidates rather than leaving this to party elites. This democratises the candidate selection process.
The Electoral College reinforces federalism and ensures smaller states receive attention during presidential campaigns rather than being ignored in favour of large population centres.
Weaknesses
Voter fatigue is a significant concern. The sheer number of elections can generate apathy and cynicism about the political process, potentially reducing participation and engagement.
The two-party system is heavily favoured by the majoritarian electoral system, leaving minimal scope for third parties or genuine independents to succeed. This limits voter choice and can make the system unrepresentative of diverse political views.
Divided government often results when the two major parties each control one chamber of Congress or different branches of government, potentially creating deadlock and making effective governance difficult.
Electoral manipulation remains possible at state level through practices like gerrymandering and restrictive voter ID laws. A fully national electoral system might provide greater fairness and consistency.
Extended campaign periods result from the primary system, increasing costs and campaign duration whilst potentially exacerbating divisions within parties.
Electoral distortion through the Electoral College can significantly exaggerate the power of smaller states and result in presidents who did not win the national popular vote, raising questions about democratic legitimacy.
Strengths and Weaknesses of the US Electoral System:
| Strengths | Weaknesses |
|---|---|
| Frequent elections provide extensive participation opportunities | Voter fatigue from excessive number of elections |
| Majoritarian system delivers clear results | Two-party system dominance limits choice |
| Federal structure respects state sovereignty | Divided government creates potential deadlock |
| Primaries democratise candidate selection | Electoral manipulation through gerrymandering |
| Electoral College reinforces federalism | Extended and expensive campaign periods |
| Multiple levels of accountability | Electoral College distortion of popular vote |
Key Points to Remember:
-
The US has four main types of elections: presidential (via Electoral College), congressional, primaries, and direct democracy measures
-
Federal elections occur on fixed schedules (presidential every 4 years, congressional every 2 years), but states control most electoral administration
-
Gerrymandering is the deliberate manipulation of district boundaries for party advantage and only applies to House elections
-
Nearly all elections use majoritarian systems (winner-takes-all), though some states employ alternatives like ranked-choice voting
-
The Electoral College awards votes based on congressional representation using the formula: , meaning each state has at least 3 ECVs
-
Reapportionment occurs every 10 years following the census, adjusting both House seats and Electoral College votes based on population changes
-
The system reflects federalism but faces criticism for voter fatigue, two-party dominance, and potential for manipulation through gerrymandering and Electoral College distortion
