Obama Up Big in California

If there was some doubt that Barack Obama would carry California, the Field Poll helps erase it.

Obama leads John McCain 54 percent to 30 percent. Among Obama supporters, 54 percent said they're very enthusiastic about their candidate, while just 17 percent of McCain supporters said that.

Though the Illinois Democrat lost his party's primary to Sen. Hillary Rodham Clinton (D-N.Y.), her absence from the ticket makes little difference. Just 9 percent of Democrats polled said that not choosing Clinton makes them less inclined to back Obama in November. More Democrats than not -- 48 percent to 40 percent -- oppose Clinton as the Democratic vice presidential nominee.
