Continuing a trend we've seen in a couple of polls now, Zogby has another national poll out today that indicates that, while Biden's entry to the race saps more support from Clinton than Sanders, his entry into the race would harm Sanders more in terms of actually capturing the nomination.
With Biden:
Clinton 44
Biden/Sanders 18
O'Malley 4
Webb 3
Without Biden:
Clinton 52 (+8)
Sanders 24 (+6)
O'Malley 3 (-1)
Webb 2 (-1)

Clinton enjoys wide leads among most demographic groups head to head against Sanders.
Mrs. Clinton leads by wide margins among men (46% to 29%) and women (58% to 20%), Democrats (60% to 21%), liberals (63% to 29%), moderates (48% to 26%), conservatives (46% to 17%), Hispanics (52% to 24%) and African Americans (65% to 20%). She and Mr. Sanders are close only among independents with Mrs. Clinton at 33% to Mr. Sanders’ 31% and 31% undecided.
The 20% support among African American voters is the highest Sanders has seen, and he performs very well among Dem leaning independents.
With Biden in the race, things change a bit, though Clinton still tends to lead among most groups.
The race is closer among men (36% for Mrs. Clinton to Mr. Biden’s 22% and Mr. Sanders’ 21%) than women (50% to 15% Sanders and 14% Biden). Mr. Sanders does best among the youngest voters (37% for Clinton to his 26% and Biden’s 12%) while Mr. Biden polls his best among voters over 50 year of age (23% to Mrs. Clinton’s 42% among 50-64 year olds, and 43% to 24% among those over 65).
While Mrs. Clinton wallops the other candidates among Democrats ((51% to 17% for Mr. Biden and 16% for Mr. Sanders), the race is very tight among independents with Mr. Sanders actually leading the way with 27% to Mrs. Clinton’s 24% and Mr. Biden’s 16%.
Zogby is not the world's best pollster by a long shot, earning a solid C in the fivethirtyeight pollster ratings, but it does confirm the general shape of the race we've seen from other pollsters- Clinton has a solid lead nationally while Biden and Sanders battle it out for second place. If Biden does not run, Clinton's position becomes more dominant
