Mayor of South Bend, Indiana, and Democratic presidential candidate Pete Buttigieg has climbed to 25 percent in a new poll surveying Iowa caucusgoers, a 16-point increase for the candidate since the last poll in September.
The CNN/Des Moines Register/Mediacom poll follows other polls showing Buttigieg in the top tier for Iowa voters. He is followed by a close fight for second, with Sen. Elizabeth Warren (D-MA) polling at 16 percent. Former Vice President Joe Biden and Sen. Bernie Sanders (I-VT) are tied at 15 percent.
Warren has dropped six percentage points since September polling. Biden dropped five and Sanders gained four.
No other candidate polled double digits in the state.
