The survey, commissioned by the Democratic Congressional Campaign Committee, found Owens at 50%, with Matt Doheny at 38% and Green Party candidate Donald Hassig polling 4%. Eight percent of voters remain undecided.
Responding to the poll, Doheny spokesman Jude Seymour told Roll Call magazine that support will be much lower for the Democrat when voters find out that Owens is "part of a job-killing agenda" of the Obama administration.
Owens, a Democrat from Plattsburgh, is fighting to survive in a district that tilts Republican in terms of voter registration, even more so after this year's congressional redistricting. Doheny, a Republican from Watertown, came within a razor-thin margin of unseating Owens two years ago.
The survey included 400 likely voters in the 21st congressional district and was conducted in late July.
