Treatment Effect
1 Direct exposure on attendees:
Voter coordination. Learn about each other’s preferences and beliefs. Platform transparency. Better understand the candidate’s platform. Platform customization. Actively influence policy by debating with the candidate.
2 Indirect exposure on non-participants:
Information sharing. Learn about the candidate’s platform from attendees in your social network (Contagious voting as in Nickerson [2006, 2008]).

Town Hall Meetings
Introduction(10 -15 minutes). Introduction to programmatic platform from the candidate. Deliberation (70-95 minutes). Rounds of questions/comments and
platform. Resolution (10 minutes). Summary of meeting proceedings and commitment to transmit information to party leaders.

In-depth analysis of the intrinsic institutional effects of town hall meetings from its policy effects by looking at meeting proceedings. Is the effect on attendees driven by horizontal communication or vertical communication, or both? Follow the process of voting contagion from attendees to other voters. Through which channels attendees share the information of the meetings with other voters?
