Champagnesocialister eller arbetarklasshöger? : Egotropiska partisympatier i Sverige 1986-2020

Sammanfattning: Previous research on egotropic voting behavior has examined specific elections and short-term periods, providing limited insights. In this study, I aim to complement and expand the understanding by investigating the phenomenon over a longer time span and specifically focusing on party sympathies of voters, which also captures behavior between elections in Sweden. Using survey data from the SOM Institute, the associations between different levels of household income and their co-variation with party sympathies within various political blocs on a left-right scale are examined through regression analysis. The study demonstrates support for the notion that voters exhibit varying party affiliations in relation to household income. However, the statistically significant results are somewhat weakened when controlling for factors such as education, gender, age, employment, and residential location. To some extent, these findings confirm previous research conclusions that higher incomes are strongly associated with sympathy for and voting for right- wing parties, whereas lower incomes exhibit a stronger relationship with sympathies for left-wing parties. A considerably weaker but similar pattern emerges for household incomes in relation to radical right-wing parties, where low-income households show a greater propensity to vote for these parties compared to high-income households.
