(CNN) - A surprising new Senate poll in Delaware shows Republican Christine O'Donnell may be in striking distance of Democrat Chris Coons.
According to the new survey from Monmouth University, the surprise Republican nominee is only 10 points behind Coons, drawing 41 percent of the vote. In a previous Monmouth poll conducted two weeks ago, O'Donnell trailed by 19 points.
But the latest Monmouth survey differs substantially from two other recent polls, including a Farleigh Dickinson survey released Thursday that showed a 21-point advantage for Coons and a CNN/Time poll released earlier this month that indicated a 19-point lead for Coons.
The latest Monmouth poll surveyed 1,171 voters between October 25-27 and carries a sampling error of plus or minus 3 percentage points.
