* Those findings noted, there is movement on the question of whether a Democrat or a Republican would do a better job of representing the district. 2 months ago, voters said by 50% to 39% that a Republican would do a better job. Today, voters by 43% to 40% say a Democrat would do a better job.

Cell-phone respondents and home-phone respondents included in this research: SurveyUSA interviewed 700 registered voters from Washington state’s newly drawn 1st congressional district, using registration based (voter-list) sample from Aritstotle of Washington DC. Of the registered voters, 563 were determined by SurveyUSA to have either already returned a ballot or to be likely to do so before the 08/07/12 deadline. This survey was conducted 100% by telephone. Respondents reachable on a home telephone (80% of likely voters) were interviewed on their home telephone in the recorded voice of a professional announcer. Respondents not reachable on a home telephone (20% of likely voters) were contacted by live operators, who hand-dialed cell phones, interviewed the respondents, asked the questions, recorded the answers, and remained on the line until the interview was complete. The U.S. House seat is vacant; Democrat Jay Inslee has resigned to run for Governor of Washington.
