April 20 (Bloomberg) -- President George W. Bush has gained against Democratic Senator John F. Kerry among voters concerned about the war in Iraq and as Bush's re-election organization has conducted a $50 million advertising campaign, two polls show.
The surveys, for Cable News Network/USA Today and ABC News/Washington Post, show Bush leading Kerry among registered voters by 3 percentage points to 5 percentage points. A third poll, by Zogby International, shows Kerry ahead of Bush by 3 points. They were conducted from Thursday to Sunday.
Representatives from both campaigns said the differences in the surveys indicate the race remains close. Presidential scholar Stephen Hess of the Brookings Institution in Washington said Bush may be benefiting from heightened worries about the war as U.S. troops confront an insurgency that has killed more than 90 U.S. military personnel over the past three weeks.
``I think it could be modestly described as a rally around the flag effect,'' said Hess, who called the poll numbers ``staggeringly good news'' for the president.
