Poll: Brown, Warren Very Close In U.S. Senate Race

A new poll says the race between Republican U.S. Sen. Scott Brown and his Democratic challenger Elizabeth Warren remains extremely close.

The UMass Lowell-Boston Herald poll released Sunday shows Brown ahead by 1 percentage point among likely voters, 49 percent to 48 percent. It also shows Warren leading by 2 percentage points among registered voters, 49 percent to 47 percent.

The margins of error were plus or minus 4.1 percentage points and plus or minus 3.7 percentage points, respectively.

Co-director of the UMass Lowell Center for Public Opinion Joshua Dyck says what the campaigns do to get out the vote is "likely to determine the winner."

The survey of 956 Massachusetts registered voters, 800 of whom were considered to be likely voters, was conducted Oct. 31-Nov. 3.
