A Sienna College poll released Saturday shows Bernie Sanders with a commanding lead in Iowa, just over one week before the state votes in the first in the nation caucuses.
Asked which candidate would be their first choice at the caucuses, 25 percent said they supported Bernie Sanders, giving the Vermont Senator a clear 7 percent lead over the rest of the field.
18 percent would vote for Pete Buttigieg, while 17 percent said they would support Joe Biden. Elizabeth Warren followed closely in fourth place with 15 percent support. No other candidate scored in the double digits.
Sanders was the clear favourite among voters aged between 18 and 29, with 40 percent of voters in this demographic saying he would get their vote.
The poll of 584 likely Democratic caucus participants in Iowa was conducted between January 20 and 23.
Iowans will caucus on Monday, 3 February.
