Democratic Sen. Jean Carnahan trails former Republican Rep. Jim Talent in a new poll that reverses previous findings in Missouri's closely watched Senate race.

The Zogby International poll of 800 likely voters, conducted Wednesday through Friday for the St. Louis Post-Dispatch, shows Talent leading Carnahan, 47 percent to 41 percent.

A Zogby poll last month showed 48 percent supported Carnahan and 40 percent in favor of Talent.

The most recent survey had a margin of error of plus or minus 3.5 percentage points. Last month's poll had a sampling error margin of plus or minus 4.5 percentage points.

Talent has gained the advantage among male voters, who preferred him by a 16-point margin. A month ago, men were almost evenly split between the candidates.

He has dramatically slashed Carnahan's lead among women. Likely female voters were almost evenly split. Last month's poll showed Carnahan with 16-point advantage among women.

Talent served in the U.S. House from 1992 to 1998 and was an unsuccessful Republican nominee for governor in 2000.

Carnahan's husband, Gov. Mel Carnahan, died in a plane crash three weeks before Election Day 2000. He still was elected to the Senate, unseating current Attorney General John Ashcroft, and his wife was appointed to the seat.
