A new Iowa State University poll finds Pete Buttigieg leading the Democratic field with 26%, followed by Elizabeth Warren at 19%, Bernie Sanders at 18% and Joe Biden at 12%.
Warren has dropped by nearly 10% over the past month.
Said pollster Dave Peterson: “Warren has seen heightened scrutiny this past month, while Buttigieg has received mostly positive attention. A little over 60% of the people who supported Warren in October still support her now, and those who switched went to Buttigieg.”
