This poll has its critics, but it is not a good omen for Dubya that after a full dose of his negative ads, his numbers are very stagnant at best. I think Kerry is doing fine right now, but he needs to put out this small fire over "name the foreign leaders who support you, Senator Kerry." It looks bad 1) because he cannot name them, and 2) touting foreign support isn't necessarily the best way to woo swing voters.
