From NBC’s Domenico Montanaro
Obama has now led in 111 straight national polls with methodologies we trust (looking back through the Pollster.com national trend), including the trackers back to Sept. 22-24 when a Gallup Tracking poll showed the race tied at 46%-46%. Since a Big Ten poll that showed McCain up 46%-45%, Obama has led in 117 of 119 polls.
