Democrat Edward J. Markey leads Republican Gabriel E. Gomez by eight percentage points among likely voters, according to a new poll of the US Senate race released late Saturday night.
The poll found Markey leading Gomez 49 percent to 41 percent. Nine percent of those polled were either undecided or did not know.
The poll, sponsored by the Springfield Republican newspaper, MassLive.com and CBS 3 Springfield, was conducted by the Western New England University Polling Institute from June 16-20. It surveyed 566 likely voters and had a margin of error of plus or minus 4.1 percentage points.
Other public polls in recent weeks have also found Markey to be leading Gomez, but by larger margins.
A UMass Lowell-Boston Herald poll released on Friday found Markey leading by 20 points.
A Boston Globe poll released on June 16 found Markey leading by 13 points.
Voters cast their ballots on Tuesday.
