NEW YORK, Jan. 16 (UPI) -- Democratic presidential hopeful John Kerry expanded his lead over the field for next Monday's Iowa Caucus, a new poll showed Friday.
Sen. John Edwards of North Carolina remained fourth at 17 percent.
"Kerry leads among Democrats, young and old voters, men and women, liberals and moderates, and those who say they are 'definitely voting' on Monday," pollster John Zogby said. "There is a three-way cluster among union voters, but Dean is the candidate who is out of the loop.
"Again, any one of the four can win this one."
