Step-By-Step, Inch-By-Inch, Obama Tip-Toes Up To Clinton's Back Door in Ohio: In a Democratic Primary in Ohio today, 02/26/08, the day the candidates debate in Cleveland, and 7 days before the votes are counted, Hillary Clinton is 6 points in front of Barack Obama, 50% to 44%, according to a SurveyUSA poll conducted for WCMH-TV Columbus, WKYC-TV Cleveland, WCPO-TV Cincinnati, and WHIO-TV Dayton. Two weeks ago, Clinton led by 17. One week ago, Clinton led by 9. Today: 6. Clinton holds her ground in greater Cleveland, greater Columbus, and greater Cincinnati. Clinton is steady among seniors, among voters focused on Health Care, among Moderates, among Pro-Choicers, and among women. Though Clinton trails among men, Obama has stopped making further inroads there. However: Among registered Democrats, Clinton had led by 21, then led by 17, now leads by 8. Among voters under age 50, Clinton had led by 9, then trailed by 2, now trails by 7. Among Pro-Life voters, Clinton had led by 11, then led by 8, now trails by 5. Among voters focused on the Economy, Clinton had led by 25, then by 21, now by 14. In greater Toledo, Clinton had led by 29, now leads by 1. Early voting favors Clinton: Among the 12% of respondents who tell SurveyUSA they have already voted, Clinton leads by 22 points. For Obama to win Ohio, he must receive at least 52% of the remaining likely voters. If Clinton gets more than 48% of the remaining Democratic Primary votes, Clinton wins the state. Because the convention delegates are allocated proportionally, a win for either candidate is not as profound as the symbolism that goes with it.
