New poll data:
The momentum in the Democratic nomination race has clearly swung toward Barack Obama. Not only has he won all of the post-Super Tuesday contests, but he has steadily gained in Gallup Poll Daily tracking to the point where he has overtaken Clinton as the national leader for the first time, holding a statistically significant lead in each of the last three tracking poll results.
Obama’s standing has improved among most Democratic subgroups over the past several days. But one of the more substantial shifts has been the changing preferences of middle-aged Democratic voters, who have moved away from Clinton and toward Obama in the past week. Obama has also made gains among three other groups that have favored Clinton throughout much of the campaign — women, Hispanics, and self-identified Democrats. Obama and Clinton are now running even among these three key groups in the most recent Gallup tracking data.
