A July 12-14 Zogby America poll, with a +/-3.1 percent MoE, found Clinton leading Giuliani 46 percent to 41 percent.
A July 9-10 Rasmussen Reports poll, with a +/-4 percent MoE, found Clinton leading Giuliani 44 percent to 43 percent.
A July 15-18 George Washington University Battleground 2008 poll, conducted by The Tarrance Group and Lake Research Partners with a +/-3.1 percent MoE, found Giuliani leading Clinton 49 percent to 44 percent.
