Hillary Rodham Clinton has jumped to an astounding 33-point lead over Barack Obama, topping her main rival among every major slice of the electorate and widening a dominating advantage she has held all summer.

Clinton got support from a full majority for the first time in any national survey about the Democratic presidential field. She is backed by 53 percent in the latest Washington Post/ABC News poll.

Obama follows far behind, with 20 percent, and John Edwards has 13 percent.

"I think it's pretty well done, don't you? All over but the voting," said Rep. Tom Petri (D-Wis.), when asked about the poll.

The contours of the survey are striking, even considering Clinton's previous edge.

Clinton leads her rivals on every major policy issue - and gets backed by an astonishing 66 percent on health care. The New York senator just released her health plan last month.

She wins backing from voters who want "strength and experience" (62 percent) as well as those who want "new direction and new ideas" (45 percent to Obama's 31 percent). She even rates as more "inspiring" than the charismatic Obama, 41 to 37 percent.
