This data has been compiled from a national telephone survey of 15,000 Likely Voters conducted by Rasmussen Reports from June 1-30, 2004. Each night, 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.
