Lång ledning för Obama

First Read påstår idag att Obama nu lett i 111 nationella opinionsundersökningar i rad.

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.
