PART A: Constructing the Priority Congruence Measures
The campaign media data of the GLES was collected over the ten weeks leading up to the election. It comprises manually coded data on the evening newscasts of the main public and private German television broadcasters ( ARD/Das Erste , ZDF , RTL , and Sat.1
Roßteutscher, Schmitt-Beck, and Weßels 2012) and the front pages of the six major
nationwide daily newspapers ( Frankfurter Allgemeine Zeitung , Die Welt , BILD ,
Sueddeutsche Zeitung , Frankfurter Rundschau , and die tageszeitung
Rossdeutscher, et al. 2012). The units of analysis are individual news reports in newscasts
and articles, respectively.
1
The policy issues included in the coding scheme of the GLES were summarised into broader issue categories. The salience of each category in the media coverage is defined as the relative number of articles or reports concerned with the issue in the context of German politics. The newspaper data also records whether an issue is the ‘major’ or the ‘minor’ issue of an article, which I take account by giving ‘major’ issues twice as much weight as ‘minor’ issues. The resulting media salience score of each issue indicates the relative number of TV news reports and newspaper articles devoted to it.
The candidate survey (Rattinger, Roßteutscher, Schmitt-Beck, Weßels, et al. 2012)
was conducted shortly after the election online and by mail among candidates of the five major political parties – the Christian Democrats (CDU/CSU), the Social Democrats (SPD), the Liberals (FDP), the Greens, and the Left. The sample of 790 includes both constituency candidates, who stood for direct election by plurality vote, and list candidates, who could be elected based on proportional representation rules.
The salience of each policy issue among candidates is measured by the relative frequency with which the issue occurs in their replies to the question ‘What are in your opinion the three most important problems with which Germany is confronted at the moment?’ in the survey. The data includes up to three issues mentioned in reply to the most, second most, and third most important problem questions, respectively. Each issue’s occurrence was weighted according to its importance (most important issues count three

1
times and second most important issues twice as much as third most important issues). In order construct the dyadic congruence measure, issue salience scores were calculated for each party separately.
In the next step, I calculate the priority congruence scores of each respondent in the post-election cross-sectional voter survey, which was conducted within eight weeks after the
election (Rattinger et al. 2011). Similarly to the candidates, voters were asked what they
thought were the most, second most, and third most important problems facing Germany at the moment. From each of the three responses, up to five issue categories are listed in the data set, in cases where a respondent included more than one issue in her response.
Respondents’ congruence scores were calculated by averaging the salience of their concerns among candidates and the media, respectively.
2
If respondents mentioned multiple issues in one response, these partial congruence scores were averaged. Each respondent’s three resulting congruence scores, for the most, second most, and third most important problems, were then combined into a weighted average, where the most important issue(s) again counts three times as much as the third most important issue(s) and the second most important issue(s) twice as much.
3
Dyadic priority congruence indicates how salient a respondent’s concerns were among the candidates of the party for which he or she declared to have voted, if any. Since
Germany has a mixed-member proportional election system and voters can make two crosses
– one for a constituency candidate and one for a party list – I take the average congruence with both parties when respondents split their ticket.
4
Collective priority congruence is constructed by averaging the five major parties’ salience levels of a respondent’s priorities, weighted by parties’ seat shares after the election as a proxy for their visibility. Figure OA1 shows the distributions of the three priority congruence variables.
2
I constructed separate TV congruence and print media congruence variables, yet they were so highly correlated (Pearson’s r = .97. p<.0005) that it makes sense to average them.
3 In Part B of this Online Appendix, I further discuss the rationale behind the weighting scheme and apply two alternative specifications.
4
Since strategic voting occurs with respect to both votes, it is difficult to tell which party reflects a voter’s ‘true’ preference (Gschwend 2007).

PART B: Testing Alternative Specifications of Priority Congruence
In the following, I explain my decision to weight citizens’ issue priorities based on whether they were mentioned as most, second most, and third most important problems. I furthermore test the robustness of the results with alternative specifications of the congruence variables.
The respondents of the voter and candidate surveys were not simply asked to provide a number of policy concerns but to express which issues facing Germany they consider most important, second most important, and third most important. If we accept the assumptions that citizens and candidates do in fact assign different levels of importance to issues; that the
‘most important problem’ (MIP) survey items capture this rank order; that issues considered more important by candidates’ are more salient in the political debate; and that the issues that citizens consider more important by citizens influence their evaluations of elites’ preferences
more strongly (cf. Krosnick 1989; Lavine et al. 1996), which should take these rank orders
into account.
In order to do so in my measures of issue salience and priority congruence, I weight candidates’ and voters’ issue mentions as follows: the second most important issues receive two thirds of the weight and the third most important issues receive one third of the weight as the most important issues. Yet, it is possible – though not likely – that the assumptions listed above are flawed and, consequently, the 3-2-1 weighting scheme is not appropriate. In particular, citizens’ rank order might not reflect their actual attitudes, whereas candidates should have spent considerable effort reflecting on their priorities. Thus, I empirically test the validity of the 3-2-1 weighting of citizens’ concerns. For this purpose, I replicate Models 1, 2, and 3 in Table 1 using two alternative sets of priority congruence measures.
For the first set of alternative variables, respondents’ congruence is still calculated based on the salience of their first, second, and third most important problems amongst candidates and in the media. Candidates’ priorities are, again, weighted based on the 3-2-1 scheme, but citizens’ priorities are not weighted. This variable thus reflects the possibility that citizens either have no clear rank order among their most important issue concerns or that the survey items included in the voter survey do not capture it.
The second specification is only based on respondents’ most important problem, ignoring the second and third issues. This variable reflects the view that citizens’ capacity and willingness to spend cognitive effort on political matters is limited and that they use
heuristics to form opinions and make choices (Delli Carpini and Keeter 1996; Lau and
4
Redlawsk 2001; Popkin 1991). Citizens’ evaluation of elite attention to their single most
important concern could be used as a heuristic to evaluate congruence more generally.
All three variants of the congruence variable are quite strongly correlated with each other (Table OB1). Tables OB2 and OB3 show the results of the estimations of Models 1, 2, and 3 from Table 1, with the alternative congruence variables substituting the weighted specification. In all models, priority congruence significantly (p<.05) predicts democratic satisfaction, confirming that the relationship is robust to different specifications of the explanatory variable. In Table OB4, I list the deviance values of all models in Tables 1, OB2, and OB3. None of the three different specifications of the congruence variable consistently fits the data better than the others. It thus does not seem strictly necessary to use the 3-2-1 weighting scheme that I use in the paper. Nevertheless, based on the theoretical arguments in favour of the weighted measure, I choose to use it in the paper.
