Senator Bernie Sanders is leading other
Democratic presidential candidates with 25% of the likely vote in Iowa, just over a week before statewide caucuses in the state, a
New York Times/Siena College poll released Saturday showed.

Sanders has gained six points since the last Times/Siena poll in October, while support for Pete Buttigieg, the former mayor of South Bend, Indiana, and former Vice President
Joe Biden has remained steady at 18% and 17%, respectively, it showed.
Sanders' gains come at the expense of his fellow progressive, Senator
Elizabeth Warren of Massachusetts, whose support dropped to 15% from 22% in the October poll, the New York Times reported.
