Alternative voting system (also called preferential voting or ranked choice voting) is an electoral system where voters rank candidates in order of preference (1st, 2nd, 3rd). If no candidate gets over 50% of first-preference votes, the candidate with fewest votes is eliminated and their votes are redistributed based on second preferences until someone wins a majority.
Quick Summary
- Voters rank candidates by preference instead of choosing just one
- Winner must get over 50% of votes to be declared
- Eliminates candidates with fewest votes and redistributes their votes
- Used in Australia’s House of Representatives elections
- Reduces vote splitting between similar candidates
How Alternative Voting Works
| Step | What Happens | Example |
|---|---|---|
| 1. Voting | Voters rank candidates (1, 2, 3, etc.) | Ahmed ranks: 1-Candidate A, 2-Candidate B, 3-Candidate C |
| 2. First Count | Count all first-preference votes | A gets 45%, B gets 30%, C gets 25% |
| 3. Check Majority | If someone has over 50%, they win | No one has 50% yet, so continue |
| 4. Elimination | Remove candidate with fewest votes | C is eliminated (has only 25%) |
| 5. Redistribution | Transfer eliminated candidate’s votes to voters’ second choices | C’s votes go to A or B based on second preferences |
| 6. Repeat | Continue until someone gets 50%+ | A now has 52% and wins |
Features of Alternative Voting System
Preferential ranking: Voters don’t just pick one candidate. They rank all candidates in order of preference. This shows who they want most and who they’d accept if their first choice can’t win.
Majority requirement: The winner must get over half of all votes. This is different from simple majority system where someone can win with just 30% if others split the remaining votes.
Vote transfer mechanism: When a candidate is eliminated, their votes don’t disappear. The votes go to whichever candidate each voter ranked next. This continues until someone crosses 50%.
Single winner per constituency: Like simple majority voting, each electoral area elects only one representative. This is different from proportional representation which elects multiple winners.
Exhaustive process: The counting can take several rounds. Each round eliminates the weakest candidate and redistributes votes. In Nigeria’s context, if we used this for gubernatorial elections, it would replace our current run-off system.
Advantages of Alternative Voting System
Prevents wasted votes: Your vote still counts even if your first choice loses. If you vote for a small party candidate who gets eliminated, your vote transfers to your second choice. This encourages people to vote for who they truly want.
Ensures broad support: Winners must appeal to over 50% of voters. They can’t win by just pleasing a small group. This forces candidates to build wider coalitions and consider different viewpoints.
Reduces vote splitting: When two similar candidates compete, they don’t split votes and lose to a less popular opponent. For example, if two Northern candidates run against one Southern candidate in Nigeria, the system prevents the Southern candidate from winning with just 40% while the North’s 60% splits between two people.
Encourages positive campaigning: Candidates want to be voters’ second or third choice, not just their first. This means less negative attacks and more focus on policies. They can’t afford to strongly attack candidates whose supporters they might need.
Stronger mandate: The winner can claim support from the majority. They have more legitimacy than someone who won with 35% in a crowded field under simple majority.
No need for run-off elections: Countries like Nigeria use run-offs when no one gets 25% in two-thirds of states. Alternative voting achieves the same result in one election, saving time and money.
Disadvantages of Alternative Voting System
Complex for voters: Ranking multiple candidates confuses some voters. In areas with low literacy rates (like some Nigerian rural communities), voters might struggle to properly rank 10+ candidates. This can lead to spoiled ballots.
Slow counting process: Counting can take days because officials must redistribute votes multiple times. In Nigeria where INEC already faces delays announcing results, adding this complexity would worsen the problem.
Expensive to implement: The system needs computers or lots of manual counters to track preference transfers. Training electoral officers costs money. Many developing countries can’t afford the technology needed for quick, accurate counting.
Tactical voting still possible: Smart voters can game the system by ranking weak candidates higher to eliminate stronger opponents early. This defeats the purpose of honest preference ranking.
Doesn’t guarantee proportional representation: A party with 40% support across the whole country might win zero seats if they always come second. Small parties struggle to win any seats even with substantial support.
Can eliminate centrist candidates early: Moderate candidates might have few first-preference votes but many second-preference votes. They get eliminated before their broad appeal becomes clear. The system can favor polarizing candidates with passionate core support.
Alternative Voting vs Other Electoral Systems
| Feature | Alternative Voting | Simple Majority | Proportional Rep. |
|---|---|---|---|
| How you vote | Rank candidates 1, 2, 3 | Pick one candidate | Vote for party list |
| Winner needs | Over 50% of votes | Most votes (can be 30%) | Share of national vote |
| Number of winners | One per area | One per area | Multiple nationwide |
| Small parties | Struggle to win | Almost never win | Can win seats |
| Counting time | Several hours/days | Same day | Few hours |
| Used in | Australia, Ireland | Nigeria, UK, USA | South Africa, Israel |
Common Exam Mistakes to Avoid
Don’t confuse with proportional representation: WAEC examiners note many students mix these up. Alternative voting still elects one winner per area. Proportional representation elects multiple winners to match party vote shares.
Don’t say “highest votes wins”: The winner needs over 50%, not just the most votes. Explain the elimination and redistribution process that continues until someone crosses the majority threshold.
Don’t just list features without explaining: When questions say “explain,” WAEC expects you to describe HOW the system works, not just mention “preferential voting” without detail.
Remember the alternative names: Preferential voting, ranked choice voting, and alternative voting mean the same thing. Use these terms interchangeably to show understanding.

Essay Question
Question: Explain four advantages of the alternative voting system. (10 marks)
Marking Guide: Award 2.5 marks for each well-explained advantage. Look for:
Sample Answer Points:
1. Prevents wasted votes (2.5 marks): In alternative voting, even if your first choice candidate loses, your vote transfers to your second preference. This means your vote continues to count throughout the counting process. Voters feel encouraged to vote for smaller parties or independent candidates they truly support, knowing their vote won’t be wasted if that candidate is eliminated early.
2. Winner has broad support (2.5 marks): The system ensures the winner receives support from over 50% of voters after preference transfers. This gives the winner a strong democratic mandate. Unlike simple majority where someone can win with 35% in a divided field, alternative voting produces winners that more than half the electorate finds acceptable.
3. Reduces vote splitting (2.5 marks): When two similar candidates compete, they no longer split the vote and lose to a less popular opponent. For example, if two progressive candidates and one conservative candidate run, the progressive votes won’t split allowing the conservative to win with minority support. The eliminated progressive’s votes transfer to the remaining one.
4. Eliminates need for run-off elections (2.5 marks): The system achieves in one election what countries like Nigeria do with run-offs. This saves the massive costs of conducting a second election. It also saves time and reduces voter fatigue from having to vote multiple times. The preference ranking essentially includes the run-off in the original ballot.
Memory Aid
Remember “RAVE” for Alternative Voting:
- Rank candidates in order
- Always need 50%+ to win
- Votes transfer when candidate eliminated
- Eliminates weakest until someone wins
