Coakley leads Brown 50 percent to 41 percent. The survey by Rasmussen Reports of 500 voters who say they are likely to cast a ballot on Jan. 19 has a margin of error of plus or minus 4.5 percent.
"Special elections typically feature low turnout," the company says on its Web site. "That’s one reason the race appears to be a bit closer than might typically be expected for a Senate race in Massachusetts. Kennedy carried 69% of the vote when he was re-elected in 2006."
One percent of those polled say they would vote for "some other candidate." Joseph Kennedy, who is running as an independent and is of no relation to the late senator, is the only other candidate on the ballot.
Seven percent said they were not sure who they would vote for.
Correction: Coakley and Brown are not in a statistical tie.
