NEW YORK, Jan. 15 (UPI) -- Sen. John Kerry, D-Mass., has pulled ahead in the tightening Iowa caucus race, a new MSNBC-Zogby poll showed Thursday.
Sen. John Edwards, D-N.C., was another point back, making it a four-man race at this juncture.
Pollster John Zogby said Kerry and Gephardt were tied among union voters as Dean's labor support slipped. He said Kerry leads among singles and college-educated voters.
"But, Dean is not in a free fall," he said. "Gephardt still has the organization, but do not count out Edwards, who leads in the central part of the state and is running strong among college graduates."
The caucus voting is Monday.
