From CNN:
Seven in 10 Democrats say they'd like to see Obama as their party's presidential nominee next year.
That figure may seem promising, but support for Obama's re-nomination has fallen 11 percentage points since June.
Despite the decline, history is on Obama's side. "In 1994, only 57% of Democrats wanted the party to renominate Bill Clinton, and he went on to win the nomination and a second term two years later," said CNN Polling Director Keating Holland.
Key elements of the progressive base are more likely to support Obama:
Liberals support Obama 79%-18, non-whites 88%-11%. Democrats support 73 Obama 73-28.
There is less support for Obama among moderates (71-28) and Whites (59-41).
