This data has been compiled from a national telephone survey of 15,000 Likely Voters conducted by Rasmussen Reports from May 1-31, 2004. Each night (except Mothers’ Day), 500 interviews with Likely Voters were conducted. National results for the survey during that time frame show that President Bush and Senator Kerry each attracted 45% of the vote. State-by-state samples carry a margin of error that varies from +/- 3 percentage points to +/- 5 percentage points depending upon the state. Data for California, Texas, and New York carries a 3 percentage point margin of error. For Florida, Illinois, Pennsylvania, Ohio, and Michigan, the margin of error is +/- 4 percentage points. For all other states, the margin of error is +/- 5 percentage points. In all cases, the margin of error is expressed with a 95% level of confidence. In some states, oversampling and supplemental interviews were used to obtain an adequate sample size for reporting purposes.
