Data were analyzed from an October 2007 deliberative poll event in Omaha, Nebraska. The focus of pre-event survey questions was on the usefulness of media sources on the coverage of the global immigration issue. The goal of the project was to promote civic engagement of citizens on an important public issue. The focus of post-event survey questions was on attention paid to media. Additionally, a post-event focus group explored public opinion on credibility of various news sources. While the deliberative poll produced some evidence of short-term effects in terms of citizens learning about the immigration issue, attitudes about media credibility appeared to be well established before the event and based on personal experiences. These beliefs may also have influenced the course of dialogue within the deliberative poll event. The method proved valuable for exploring in-depth views about controversial issues.
