A new poll gives Massachusetts Senator Ed Markey a five-point lead over his primary challenger in the race for the Democratic Party nomination. 

The Emerson College survey finds Markey ahead of Congressman Seth Moulton by a margin of 37-to-32 percent with 29-percent undecided. 

The poll of one-thousand registered voters was taken earlier this week. 

The margin of error is plus or minus three-percent.
