A new poll conducted by University of Massachusetts Amherst has Elizabeth Warren leading Senator Scott Brown by a 43 to 39 percent margin in the high profile race for Brown’s senate seat. Warren’s lead is within the poll’s 4.4 percent margin of error, but the poll contains a number of troubling trends for the incumbent Republican.

As UMass Amherst political scientist Brian Schaffner says, “The race is a dead heat and [Brown's] support is well under 50 percent, which usually means difficulty for an incumbent, especially this far out from Election Day.”
