Here's a surprising number from the new Gallup Poll: Obama has, for the first time in Gallup polling, taken a double-digit lead over Hillary among national Dems. He leads her 51%-39%.

Separately, in another startling finding, nearly three out of four Dems say Obama will be the nominee (73%), versus only a fifth (20%) who say Hillary will.

Obama holds a much slimmer lead in Gallup's national tracking poll, but as MyDD's Jonathan Singer, who first flagged these numbers, points out, the stand-alone poll appears to be bigger "news," which "could serve to reinforce the meme that Obama is pulling ahead" and is running away with the race.
