Filtering: 2,100 California adults were interviewed by SurveyUSA 05/04/07 through 05/06/07. Of them, 1,730 were registered to vote. Of them, 456 were identified by SurveyUSA as likely to vote in the 02/05/08 Republican California Primary. 667 were identified by SurveyUSA as likely to vote in the 02/05/08 Democratic California Primary. Results here are based on interviews with Likely Primary Voters. Because SurveyUSA changed the exact question wording it used for this 05/07/07 release, to name more candidates in the Republican Primary and to name fewer candidates in the Democratic Primary, SurveyUSA does not here produce tracking graphs, since an identical, apples-to-apples comparison is not possible. However, data from SurveyUSA's 04/02/07 release is available for comparison here.
