KERRY EDGES AHEAD?

Different poll of polls sites show Kerry edging ahead in the past couple of days. RealClearPolitics, the excellent right-of-center site, shows its narrowest lead for Bush yet, with Kerry at his highest point since the first debate, when he took off. Electoral-Vote.com shows a big Kerry win. (Slate shows a tiny tilt back toward Bush.) Fox shows a small Kerry lead nationally. All of these are so close they could go either way. But when one candidate seems to be gaining in the last day, that matters.
