There was only originally going to be one post on this site, but a question was asked on Twitter about the need for tactical voting in the first place, so I thought I would explain.
First Past the Post
The electoral system in this country is messed up. It relies on something called “First Past the Post” which invariably produces a skewed result that unfairly puts what is usually the largest minority into office with a majority of the MPs in the House of Commons.
The country is divided up into 650 constituencies by the Boundaries Commission. These do change from time to time and are referred to as “boundary changes.” Each constituency elects an MP to sit as a representative in the House of Commons. However, the winning MP is simply the person to garners the most votes within the constituency. There is no requirement for the MP to attain more than 50% of the vote, no run-off votes, just a single one-off vote in which the candidate with the most votes wins, hence “First Past the Post”. This means constituencies can have an MP that the majority did not vote for.
Under this system, the votes cast for the candidates that did not win in their constituency do not go anywhere. They have no ability to influence the outcome of the election either locally or at a national level. In the 2017 general election, around 46% of the votes cast did not go towards the election of a candidate. There have been elections in recent history where this percentage exceeds 50%.
It is also worth noting that candidates are, under electoral law, elected as individuals. In the eyes of the law their party does not matter. This is why the many MPs who have changed parties over the recent months are under no obligation to resign their positions and hold by-elections to get themselves re-elected under their new party despite the complaints of many who do not understand the system.
Formation of the Government
The party that forms the government is the one that has the most elected candidates. Due to the way that constituencies are organised, this can result in the number of seats attained by each party being out of proportion to their share of the vote nationally. For example, in the 2015 general election, the Conservatives polled 36.9% of the vote yet wound up with 330 seats (50.1%) of the seats, Labour polled 30.4% and only attained 232 seats (35.7%), while the SNP polled 4.7% and got 56 seats (8.6%).
It is assumed that the leader of the party with the most seats will be appointed the Prime Minister. Strictly speaking, the person who becomes Prime Minister is the person who has the confidence of the House of Commons. We have no ability to directly elect this person. As has been shown with the accession of Boris the Liar to the position of PM, it was only Conservative Party members who elected him as leader of his party, and an assumption because of numbers (and a failure to challenge him by the opposition).
Once this individual has been to see the Queen, they then set about making ministerial appointments, usually from the ranks of MPs in their own party. Neither we nor Parliament have the ability to question or remove these people from office.
Pros and Cons
There are two main arguments in favour of First Past the Post.
The first is that it allows a specific individual to be accountable to their constituents. The constituency has the power to determine who represents them and when to remove them rather than voting for a party and having a candidate imposed upon them. The idea is that this creates a personal connection with the constituency.
The second is that it results in a majority government which means that the party that is granted power is better able to get its work through Parliament than if they had to deal with a coalition partner.
There are, however, flaws in these arguments.
Other electoral systems do exist which would allow voters to retain control over who represents them. What we lose by using FPTP is the ability to have representative government in this country.
Many of the underlying problems in this country come from the fact that governments are allowed free reign for five years once elected and are usually able to do so with no opposition owing to the fact that they generally will have a majority of the MPs. The opposition will continue to raise points, raise amendments, and challenge the government in order to try and hold them to account, but in the end, because they have a majority in the House, they can railroad their legislation through without issue most of the time.
The net result of such a situation is that some sections of the population are not represented in the government’s program. We have seen this particularly in the regions of England and Wales where areas have been neglected and are not a priority for government investment. This is why the loss of funding coming from the European Union will be damaging to such areas. It has resulted in people being “left behind.”
In the situation where a coalition exists, multiple parties have to come together in order to produce a shared program for government. This requires compromise between the parties but also means that the larger partner cannot guarantee the consent of their smaller partner(s). Since no party has an overall majority, the possibility for real opposition in the House of Commons rises and the ability for the opposition parties to have more of an influence is also greater.
Coalitions are much more of a feature in countries which use forms of Proportional Representation. This is because the numbers of members returned from each party more closely represents the percentage of the vote they gained from the electorate. Even if we compare with the D’Hondt system of proportional representation used in our European Elections in which multiple MEPs are returned for each electoral region, it produces a far more representative result than FPTP does and would give a higher probability of returning coalition government if used nationally in this country.
The Tactical Voting Requirement
The need for tactical voting exists because First Past the Post does not allow us to directly elect the government or its leader (the Prime Minister) and does not produce a representative government. It also has a habit of routinely discarding the votes of people who do not vote for the winning candidate.
The only way for the electorate to effect a change of government is to decrease the number of MPs the party in power has and increase the number for another party. Unfortunately, First Past the Post is working on a constituency level and because of the way those constituencies are constituted by the Boundaries Commission, this can be difficult to achieve. It requires widespread disaffection with the government to effect a change.
The Boundaries Commission when it redraws constituencies tends to ensure that like voting areas are bound together to produce a clear result intended to maximise the vote of the constituents. What this results in is constituencies which are either “safe” (i.e. where one party is usually pretty much guaranteed to win even if they put up the worst candidate imaginable) or “maginal” (i.e. two or more parties are in contention and either can win the seat).
Tactical voting is the intention to vote in a manner designed to remove the sitting MP (or their party) from your constituency. In a “safe” seat, this is somewhat harder to do largely because there will be bigger percentage of loyal voters who always vote for the same party irrespective of leadership or policies. In a “marginal”, the difference between the parties in contention could be a few thousand votes or less. This could be the product either of a balance in the number of loyalists between the parties involved, or the exact opposite where there are a larger proportion of floating voters.
So, you are in a marginal constituency where the Conservatives and Labour are in contention and the Tories have the sitting MP, the objective would be to remove that Tory MP. Irrespective of where (if anywhere) your own political inclinations lie, voting for the Labour candidate would be the action most likely to produce the removal of that Tory MP even though it would give you an MP that you do not necessarily support. If enough people in your constituency act in the same way then you will succeed and you will have removed a Tory MP from their seat thus potentially contributing to taking the Tories out of power.
In the current situation, it may be more complicated than simply voting for the party that came second. It is therefore important to seek out as much information as possible including local polling and organised tactical voting sites before coming to a decision about the best way to tactically vote. It should also be noted that campaigning does change things so it is best to reassess the situation close to polling day.
Conclusion
Put simply, tactical voting is just the action of voting against a (usually) sitting candidate purely to remove them in favour of an alternative candidate who stands a chance of winning.
It is a very negative way of voting as it involves voting for a “least worst choice” rather than for someone you actually want to win. Unfortunately, the nature of our flawed First Past the Post system necessitates this thinking some times with the result that we are locked into what is essentially an unrepresentative two party system with no hope of changing it. There are currently proposals around to reduce the number of MPs down to 600 which, according to some analyses, will increase the number of safe Conservative seats and make it harder to remove them from office, so the situation could potentially get worse rather than better.
