A research team from the Psychology Department at New York University, headed by Professor Yaacov Trope and supported by the National Science Foundation, is investigating the cognitive causes of voting behavior, political preferences, and candidate evaluations throughout the course of the 2008 U.S. Presidential election. This stage of the study focuses on the information people use to inform evaluations during the last few weeks before the election. They seek respondents of all political leanings from all over the country (and from the rest of the world) to complete a 15-minute questionnaire, the responses to which will be completely anonymous.
If you are interested, the survey is here.
As a side note, you have no idea how hard it is to get people to volunteer to provide reliable data so folks can conduct this kind of social science, so if you have 15-20 minutes to spare to answer the questions, please do so.

As requested by the study authors, I have turned off comments so as to not compromise the integrity of the study.
