STATEMENT OF METHODOLOGY FOR HEAD-TO-HEAD 2008 PRESIDENTIAL PAIRINGS SurveyUSA regularly conducts separate but concurrent statewide public opinion polls in each of the 50 states. Results from these 50 State Tracking Polls are released on SurveyUSA’s website. Each time SurveyUSA conducts 50 separate but concurrent statewide public opinion polls, at least 30,000 Americans are interviewed, typically over 3 consecutive days, sometimes 4. At least 600 adults age 18+ are interviewed from each state. SurveyUSA asks if the respondent is registered to vote. Approximately 80%, or 500 of the 600 adults in each state, tell SurveyUSA they are registered to vote.  In June 2006, SurveyUSA began adding to its concurrent statewide opinion polls a series of questions that began: "If there were an election for President of the United States today, and the only two candidates on the ballot were [Republican candidate] and [Democrat candidate], who would you vote for?" SurveyUSA systematically worked through the most obvious candidates for president. We polled as many probable pairings each month as we were able. As of 11/13/06, we have completed 60 probable Head-to-Head Pairings. These are the Head-to-Head Pairings that SurveyUSA makes available. For each pairing, there are 51 possible outcomes: one for each of the 50 states and 1 for the District of Columbia. 60 possible pairings x 51 geographies for each pairing equals more than 3,000 separate poll outcomes. More than 200,000 interviews have been completed. SurveyUSA polls are conducted by telephone. In 48 states, respondents who answer the phone hear an introduction in the digitally mastered voice of a TV news anchor. In Montana and North Dakota, respondent cooperation is first secured by a headset operator. In all states, respondents hear questions asked by a professional announcer. Respondents hear questions asked identically. Respondent households are selected at random, using Random Digit Dialed (RDD) sample provided by Survey Sampling, of Fairfield CT, unless otherwise indicated on an individual poll report. Within the report, you will find: the geography that was surveyed and the date(s) interviews were conducted. The number of respondents who answered each question and the margin of sampling error for each question are provided. For each state, the entire adult respondent population is weighted, where needed, according to age, gender, ethnic origin and geographical region, so that the sample should reflect the actual demographic proportions in the population, using most recent U.S. Census estimates. For the 2008 Presidential Pairings, unregistered voters are then excluded, and the results from registered voters are reported. 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. It is difficult to quantify the errors that may result from these factors. Fieldwork for surveys in Montana and North Dakota was done by Western Wats, of Orem, UT. Fieldwork for all other states was done by SurveyUSA of Verona, NJ.

Definitions For those survey results which include data crosstabbed by "generation" the definitions are:    Generation Birth Years  Gen Y  1979 to present  Gen X  1966 to 1978  Jones  1954 to 1965  Boomers  1942 to 1953  Mature   1941 and before For those survey results which include a "Region" crosstab, the regions are defined here. Head-to-Head Pairings The 60 available pairings appear below in a list, alphabetized by the candidate’s last name. To make it easier to find a candidate, each Head-to-Head pairing appears twice. For example, the Head-to-Head pairing for Clinton vs Giuliani appears alphabetized both in the Cs and in the Gs. For this reason, there are 120 rows below, mapped to 60 total pairings. 1 Allen vs Clinton 2 Allen vs Gore 3 Bayh vs McCain 4 Bayh vs Giuliani 5 Biden vs McCain 6 Biden vs Giuliani 7 Brownback vs Clinton 8 Brownback vs Gore 9 Brownback vs Edwards 10 Bush vs Gore 11 Clark vs McCain 12 Clark vs Giuliani 13 Clinton vs McCain 14 Clinton vs Giuliani 15 Clinton vs Romney 16 Clinton vs Gingrich 17 Clinton vs Rice 18 Clinton vs Frist 19 Clinton vs Brownback 20 Clinton vs Huckabee 21 Clinton vs Allen 22 Clinton vs Tancredo 23 Clinton vs Hagel 24 Edwards vs McCain 25 Edwards vs Giuliani 26 Edwards vs Romney 27 Edwards vs Gingrich 28 Edwards vs Rice 29 Edwards vs Frist 30 Edwards vs Brownback 31 Edwards vs Huckabee 32 Feingold vs McCain 33 Feingold vs Giuliani 34 Feingold vs Romney 35 Feingold vs Gingrich 36 Feingold vs Rice 37 Frist vs Clinton 38 Frist vs Gore 39 Frist vs Edwards 40 Gingrich vs Clinton 41 Gingrich vs Gore 42 Gingrich vs Edwards 43 Gingrich vs Feingold 44 Gingrich vs Warner 45 Giuliani vs Clinton 46 Giuliani vs Gore 47 Giuliani vs Edwards 48 Giuliani vs Feingold 49 Giuliani vs Warner 50 Giuliani vs Kerry 51 Giuliani vs Clark 52 Giuliani vs Obama 53 Giuliani vs Richardson 54 Giuliani vs Bayh 55 Giuliani vs Vilsack 56 Giuliani vs Biden 57 Giuliani vs Sharpton 58 Gore vs McCain 59 Gore vs Giuliani 60 Gore vs Romney 61 Gore vs Gingrich 62 Gore vs Rice 63 Gore vs Frist 64 Gore vs Brownback 65 Gore vs Hagel 66 Gore vs Huckabee 67 Gore vs Allen 68 Gore vs Bush 69 Gore vs Tancredo 70 Hagel vs Clinton 71 Hagel vs Gore 72 Huckabee vs Clinton 73 Huckabee vs Gore 74 Huckabee vs Edwards 75 Kerry vs McCain 76 Kerry vs Giuliani 77 Kerry vs Romney 78 McCain vs Clinton 79 McCain vs Gore 80 McCain vs Edwards 81 McCain vs Feingold 82 McCain vs Warner 83 McCain vs Kerry 84 McCain vs Clark 85 McCain vs Obama 86 McCain vs Richardson 87 McCain vs Bayh 88 McCain vs Vilsack 89 McCain vs Biden 90 Obama vs McCain 91 Obama vs Giuliani 92 Obama vs Rice 93 Reagan vs FDR 94 Rice vs Clinton 95 Rice vs Gore 96 Rice vs Edwards 97 Rice vs Feingold 98 Rice vs Warner 99 Rice vs Obama 100 Rice vs Sharpton 101 Richardson vs McCain 102 Richardson vs Giuliani 103 Romney vs Clinton 104 Romney vs Gore 105 Romney vs Edwards 106 Romney vs Feingold 107 Romney vs Warner 108 Romney vs Kerry 109 FDR vs Reagan 110 Sharpton vs Giuliani 111 Sharpton vs Rice 112 Tancredo vs Clinton 113 Tancredo vs Gore 114 Vilsack vs McCain 115 Vilsack vs Giuliani 116 Warner vs McCain 117 Warner vs Giuliani 118 Warner vs Romney 119 Warner vs Gingrich 120 Warner vs Rice Trademark & Copyright SurveyUSA® is a registered trademark of Hypotenuse Inc. © 2007 SurveyUSA.
