The first two graphs display the positions of selected social democratic parties in Europe on a two-dimensional spatial map, constructed on the basis of 30 salient issue statements related to strongly relevant policy issues in the current political debate. The most salient issues were selected by a team of academics and experts, based on a close examination of the parties' platforms and political (media) discourse. Each of the statements pertains to a policy proposal that can be framed as either “left-“ or “right-wing”, “libertarian” or “authoritarian”. The statement answers are 5-point scales with answer categories ranging from “completely disagree”, to “disagree” to “neutral” to “agree” to “completely agree”. The positions of parties on these statements are coded in accordance with their official stances on the issues, as expressed by their published policies, campaign documents and media appearances. All major parties were also asked to position themselves and provide excerpts from their party manifesto or other formal documentation. These self-placements of parties were subsequently compared with the expert coding. Discrepancies were communicated to parties over several rounds until there was full clarity and authorisation of their final issue positions.
The spatial map is constructed on the basis of the aggregate positions of the parties on the two dimensions (the left-right dimension and the libertarian-authoritarian dimension). The precise party position is located in the centres of the ellipses. The ellipses represent the standard deviations of the party answers to all statements used to construct each axis. Thus, parties in favour of both left- and right-wing policy proposals have a wider ellipse on the left-right axis; parties in favour of both libertarian and authoritarian policy proposals have a lengthier ellipse on the libertarian-libertarian axis.
How were actual voters and sympathisers identified?
All voter and party positions are based on the Election Compass party position and user data respectively[1]. Social democratic voters were selected on the basis of their vote intention and past voting choice. They reported that they voted for a social democratic party in the most recent election and indicated that they will vote for a social democratic party in the upcoming election in each country[2].
Identifying social democratic sympathisers was done by assessing the vote propensity of respondents for the social democratic party. Sympathisers are respondents that give a score of 8, 9 or 10 on a 0 to 10-point scale question “How likely is it that you will ever vote for this party (where 0 is "very unlikely" and 10 is "very likely"), but reported an actual vote intention for another party. To avoid overlap, respondents who gave the social democratic party a vote propensity of 8 or higher but also said they voted for social democrats were logically excluded from the pool of sympathisers (as they were already counted as core voters).
[1] For Austria, we have based the voter map on panel survey data, where we asked the 26 issue-statements included in the VAA "Wahlkabine". The "Wahlkabine" party positioning data was used to generate the spatial map for the Austrian strategy debates. The same issue-statements were used to position SPÖ voters and contemplators.
[2] An important note is that for France, we use voter positional data from the first round of the Presidential elections, as we did not field a VAA for the French legislative election. Thus, these voters were segmented on the basis of the vote intention and vote propensity for Benoit Hamon (presidential candidate for the French Socialist party) and Emmanuel Macron (presidential candidate for En Marche). Nevertheless, given the proximity of the two elections, and the fairly similar results (En Marche winning both first rounds with about 8 million votes and PS obtaining about 2 million votes), the French maps portray a rather accurate position of PS and En Marche voters.
