An Emerson College Polling Society poll released Monday showed former Secretary of State Hillary Clinton beating Sen. Bernie Sanders (I-VT) 51 percent to 43 percent in Iowa.

Clinton’s eight-point lead is little changed since the previous Emerson poll released ten days ago, which showed Clinton leading Sanders 52 percent to 43 percent. However, polling of Iowa Democrats has shown little consensus, as some recent polls suggest Sanders is leading in the Hawkeye State while others project a neck-and-neck contest.

The Emerson College Polling Society poll was carried out Jan. 29-31 by an automated telephone program, surveying 300 likely Democratic caucusgoers with a margin of error of 5.6 percentage points.
