Romney had 35 percent, down from 39 percent in Saturday’s poll.
Meanwhile, Rep. Ron Paul (Texas) and former Utah Gov. Jon Huntsman are seeing gains.
Paul remains in second place but Huntsman is now clearly in third. In Saturday’s poll, he, Newt Gingrich and Rick Santorum were virtually tied for that spot.
The Texas congressman received 20 percent while Huntsman had 11 percent.
Gingrich had 9 percent and Santorum, who’s been steadily dropping in the poll, was down another percentage point to 8 percent.
