The Zogby Interactive poll showed that Obama, the junior senator from Illinois, would beat McCain, the GOP front-runner, or Huckabee, the former Arkansas governor.

Obama would beat McCain in a national election, with 47 percent supporting Obama and 36 percent supporting McCain, the poll indicated. In a match-up with Huckabee, Obama would win 49 percent to 34 percent.

The poll also found that presidential hopeful Hillary Clinton would lose to McCain, but narrowly defeat Huckabee, in the general election.

Running against McCain, the New York senator would lose 37 percent to 42 percent. She would, however, defeat Huckabee 40 percent to his 37 percent, the poll indicated.

The poll of 7,468 voters nationwide was conducted Feb. 8-11. It has a margin of error of 1.2 percent.
