About this Poll
578 registered Hoosier voters likely to participate in the May 6 Democratic primary prefer Barack Obama to Hillary Clinton. Obama received 50% of the support and Clinton received 45%, with 5% undecided (margin of error +/- 4.2).

This SurveyUSA poll was conducted by telephone in the voice of a professional announcer. Respondent households were selected at random, using a registration based sample (RBS) provided by Aristotle, of Washington DC. All respondents heard the questions asked identically. The calls were conducted on April 14, 15, and 16. Calling was completed before the debate between Hillary Clinton and Barack Obama in Pennsylvania began on the 16th. The number of respondents who answered each question and the margin of sampling error for each question are provided. Where necessary, responses were weighted according to age, gender, ethnic origin, geographical area and number of adults and number of voice telephone lines in the household, so that the sample would reflect the actual demographic proportions in the population, using most recent U.S.Census estimates. In theory, with the stated sample size, one can say with 95% certainty that the results would not vary by more than the stated margin of sampling error, in one direction or the other, had the entire universe of respondents been interviewed with complete accuracy. There are other possible sources of error in all surveys that may be more serious than theoretical calculations of sampling error. These include refusals to be interviewed, question wording and question order, weighting by demographic control data and the manner in which respondents are filtered (such as, determining who is a likely voter). It is difficult to quantify the errors that may result from these factors. Fieldwork for this survey was done by SurveyUSA of Verona, NJ
