Long term factors affecting voting behaviour include class, gender, age, ethnicity, region and level of education.
In 2019, leadership was an issue for both major parties, with neither Johnson nor Corbyn being universally liked or respected.
Party image, campaigns, media and turnout are other examples of short-term factors that influence voter behaviour.
Short term factors refer to the idea that we behave like consumers, voting the way that best fits our preferences.
Voters with few or no long-term party loyalties, who therefore tend to vote differently in different elections, are referred to as ‘floating voters’.
Class was seen as the key to understanding voting behaviour in the UK until the 1970s.
In 1967, Peter Puler famously declared that ‘Class is the basis of British party policies; all else is embellishment and detail.’
The stable two-party system of the era after World War Two was largely a reflection of class alignment, when people associate themselves with a class and firmly believe that they belong to it.
Partisan alignment is when voters have a very strong, long-term connection with one political party and their support for it is very certain, regardless of who leads it or policy modifications.
In recent years there has been a rise in both class and partisan dealignment, possibly for reasons such as increased education, changing class system, less clear-cut lines between social classes, and ideological change.
Class has become a much less important factor in determining voter behaviour.
By 2005, just 10% of voters claimed to be ‘very strong’ party identifiers.
In 2017, the Conservatives performed equally well among ABC1 voters and C2DE voters.
In 2019, the Conservatives outperformed Labour across all social classes, even doing better among C2DE voters than among ABC1 voters.
Traditionally, the main gender bias in the uk was that women were more likely to vote conservative than men.
In 1997, Labour was supported by an equal number of women and men.
In 2015, men were more likely to vote conservative in all age groups under 50, but only by 2%.
The gender gap in 2019 was small and only among the young.
There has always been a general tendency for conservative support to increase with age.
Labour has tended to do better with younger voters, especially after 2015 when jeremy corbyn became leader.
Black and ethnic minority [bme] voters have usually voted labour, possibly due to the party’s association with a pro-immigrant stance.
During the 1980s, it became increasingly topical to talk about the UK’s ‘North-South divide’.
In 2017, there was a swing towards Labour in London and the South (perhaps due to these being Remain areas) as well as a small swing in Wales.
Historically, Labour MPs have dominated in Scotland. This changed with the 2014 Scottish Independence Referendum, which caused the SNP to become the dominant party.
Rational choice theory suggests that individuals make rational choices and achieve outcomes that are aligned with their own best interests.
During the 1980's, outside of London, Labour held only a few seats south of a line from the Bristol Channel to the Wash, while Conservative support declined in the north of England as well as Scotland and Wales.
Issues are not always significant in elections, as in 1992, 2017 and 2019, Labour policies were more popular than the Conservatives’ but the Conservativesprevailed in all three elections nonetheless.
In 2019, the Conservatives polled consistently well across England and most of Wales, moving into many traditional Labour heartlands.
Ethnic minority groups often experience lower income levels and higher unemployment compared to white groups, possibly linking ethnic minority support for Labour to social class.
The importance of leaders was greatly enhanced in 2010 by the introduction of televised debates between the candidates of the three leading parties.
In 2015, Labour had a lead of 42% among voters with a Black African or Caribbean heritage.
Having the ‘wrong’ policies can damage a party, as Labour demonstrated in 1983 when its manifesto contained commitments to extend nationalisation, increase taxation and boost public spending, leading to a perceived loss in ‘electability’.
Successful leaders usually need to demonstrate a number of qualities, including accessibility, trust and strength.
The Scottish Independence Referendum in 2014 radically realigned politics in Scotland, with the SNP going from 6 seats to 56 between 2010 and 2015, and the party has maintained its dominance since.
In 2017, Labour had a strong lead among BME (Black and ethnic minority) voters with 77% of BME votes.
Between 2015 and 2017, increased support for the Conservatives was noted among British Indians, particularly Hindus. The number of Hindus that voted Conservative went up from 30% to 40% over this time period
Issue voting is linked to the rational choice model of voting, which suggests that, behaving like consumers, we consider our own self-interest and preferences.
Governing competence is the perceived ability of the governing party in office to manage the affairs of the state well and effectively.
In an age of class and partisan dealignment, parties place increasing faith in leaders and leadership to win elections.
Even prior to 1997, the labour party averaged mid-40 seats in Scotland.
