Abstract
The 2015 study consists of three main complementary components: The Post-election survey, the Panel / Rolling Cross-Section survey, and the Candidate survey. The main difference compared to previous studies relates to the mode of data collection; the main emphasis was now moved towards web interviews. The other main innovation was the addition of a four-wave panel survey. As in 2011, novel thematic modules of particular salience to researchers were included in the different surveys, while keeping the necessary continuity in the core questionnaire of the Post-election survey for comparison with previous waves.
Post-election survey:
The post-election survey consists of 5,337 web and telephone interviews. The survey was done in a sequential mixed mode with web offered as the first option: 82% responded in this way, while 18% responded by telephone. The sampling was based on a representative sample of 2’600 Swiss citizens with an oversampling of small cantons to have at least 80 interviews per canton. An additional oversampling was done in the cantons of Zurich, Geneva, and Ticino.
Panel / Rolling cross-section (RCS):
New for the 2015 study is a panel survey that studies the evolution of opinion and vote intention/choice during the different phases of the election cycle. Four waves were conducted: the first before the main campaign period, the second during the campaign, the third after the elections, and the fourth after the election of the Federal Council. 11’073 individuals responded to the first wave and 6’552 responded to the first three waves. The second wave was conducted as a Rolling cross-section, where around 120 individuals were interviewed daily during 61 days.
A media analysis was also conducted in the context of this survey.
Candidate survey:
The candidate survey was carried out among all candidates for the National Council and the Council of States in the framework of the Comparative Candidate Survey (CCS) project, based on the Round II questionnaire. The survey collects data on the biography, campaign activities, and policy position of the candidates. Among others, the information gathered makes possible the study of underlying factors of candidates’ electoral success, as well as of issues of representation and linkage between voters and elites.

Sampling
Sampling Procedure
Simple random sample of 29'500 persons from the whole of Switzerland with Swiss nationality aged 18 or older on the day of the elections. The sample is based on a individual register sampling frame maintained by the Swiss Federal Statistical Office (FSO).
Response Rate
Response rates per wave: First wave: 37% Second wave: 74% Third wave: 69% Fourth wave: 75% For the first wave, respondents were contacted by letter for a web interview. The first contact was a pre-notification letter with information on the survey and a flyer with past results. The second letter included the URL to participate in the survey, a personal login code, as well as a postal cheque of 10 Swiss francs that respondents could cash at any post office. Two reminders were also sent. At the end of the survey, respondents were asked to provide an email address for contact in subsequent waves. A raffle of 5 iPads, conditional on participating in the three first waves, was organized to boost enrollment in the panel as well as to reduce attrition. The second wave was conducted as a rolling cross-section survey (RCS) that started on August 17 and lasted for 60 days. The aim was to measure the evolution of opinions and vote intentions during the last phase of the campaign. Around 120 respondents participated each day. The invitations were sent by email with two reminders spaced close apart because to reduce the field time of each address. Pre-notification letters were sent weekly to inform about the email invitation to boost response rates. The third wave was conducted immediately after the federal elections. Those who had not provided an email address in the first wave were contacted by letter, the others by email. Additionally, a pre-notification letter was again sent for those invited by email. Finally, a fourth wave was conducted among all those who had participated in the third wave and for whom an email was available. This wave was timed to be just after the election of the Federal Council.
Weighting
Three weighting variables are provided: - weight_t: Turnout weight to correct for the overrepresentation of voters in the sample. This is meant to be used in conjunction with the combined W2&W3 turnout variable "W2_3_voted" / - weight_p: Party choice weight to correct the distribution of votes according to the official results. This is meant to be used in conjunction with the combined W2&W3 vote choice variable "W2_3_f11800main7" / - weight_tot: Combined turnout and party choice weight
