SurveyUSA’s poll in Florida released last Friday, 01/25/08, the day before the South Carolina Democratic Primary, showed significant narrowing in the Democratic contest, with Barack Obama gaining material ground against Hillary Clinton. The question was: would Obama gain additional ground in Sunday 01/27/08 SurveyUSA polling, after the size of his South Carolina win was known? Preliminary answer: No. Data collected on Sunday 01/27/08 showed Obama gaining no additional ground on Clinton after South Carolina. Sunday interviews are here. Interactive tracking graphs, a SurveyUSA exclusive, are here. Additional data is being gathered tonight, 01/28/08, Primary Eve, and will be posted here as soon as it has been analyzed.
