Pete Buttigieg, the mayor of South Bend, Indiana, is the new frontrunner in Monmouth University's poll of Iowa Democratic presidential caucusgoers. In the poll, released Tuesday, Buttigieg got support from 22 percent of likely caucusgoers, jumping 14 percentage points from Monmouth's last poll in August. Former Vice President Joe Biden lost 7 points, falling to second place with 19 percent support, and Sen. Elizabeth Warren (D-Mass.) lost 2 points, coming in at 18 percent. The only other candidate with double-digit support was Sen. Bernie Sanders (I-Vt.), who gained 5 points to 13 percent support. When first and second choices were combined, Buttigieg led Warren 37 percent to 35 percent.
Buttigieg's support increased across all major demographics. At the same time, only 28 percent of likely caucus goers said they are committed to their candidate, and most said they are open to the possibility of switching contenders. Monmouth conducted the poll Nov. 7-11 among 451 likely Democratic caucus goers; its margin of sampling error is ±4.6 percentage points.
