Sen. Scott Brown (R-Mass.) and Elizabeth Warren (D) are tied, according to a new Boston Globe poll released Monday. The survey stands in contrast to several other recent polls showing Warren holding a slight lead.

Brown and Warren are tied at 47 percent apiece among those likeliest to vote in Massachusetts, according the poll, which was conducted by the University of New Hampshire Survey Center from Wednesday through Sunday. In the previous survey, conducted in late September, Warren held a slight, 43 percent to 38 percent advantage

The new poll comes as other recent surveys have shown Warren leading Brown slightly. The Real Clear Politics average of the latest polling in the race shows Warren with a nearly four-point advantage. The Fix moved the Massachusetts Senate race from the "tossup" category to "lean Democratic" last Thursday, a reflection of Warren’s momentum in the contest. 

President Obama is on pace to win Massachusetts easily, but a shrinking lead over Mitt Romney in the Bay State could be helping Brown, the new poll shows. The president’s 27-point lead has shrunk to 14. 

Brown’s retained his personal popularity in the Boston Globe poll, while Warren’s has slipped a bit. The Republican’s favorable/unfavorable split in the new poll is 54 percent/37 percent, while Warren’s is 49 percent/42 percent. In the last poll, Brown’s split was 53/33 and Warren’s was 53/36.

The two candidates are scheduled to debate a final time on Tuesday, if the effects of Hurricane Sandy don’t prevent the meeting from taking place.
