Senator Amy Klobuchar has double-digit support for the first time in her bid for president, according to a new Emerson College poll which puts her at 10 percent in Iowa — a four-point jump since the last poll by the Des Moines Register. Joe Biden remains in the lead at 23 percent with Bernie Sanders and Pete Buttigieg close behind, but Elizabeth Warren dropped to fourth place at 12 percent. Klobuchar is one of just six candidates who have qualified for the sixth Democratic presidential debate December 19th in Los Angeles.
