A new poll from the University of Massachusetts-Lowell and the Boston Herald finds Sen. Scott Brown (R-Mass.) and challenger Elizabeth Warren (D) deadlocked, 49 to 48 percent.
Brown's one-point edge is within the survey's 4.1 point margin of error, but it is the only poll in the past nine surveys of this race listed on the RealClearPolitics average to show the senator up at all. Seven recent polls give Warren the edge. One Boston Globe poll showed the race tied if you include voters leaning one way or the other; without "leaners" Brown leads by two points. Another automated survey not listed, from the Republican firm Kimball Political Consulting, gives Brown a two-point edge.
In September, the same UMass/Herald poll gave Brown a four-point lead.
