Sanders leads; Warren, Buttigieg, Biden chasing in Iowa poll
With only three weeks to go before the Iowa caucuses, a poll released by the Des Moines Register Friday shows Senator Bernie Sanders has taken a narrow lead in a tight battle with three rivals.
Sanders received support from 20% of respondents in the poll, with the next three candidates - Senator Elizabeth Warren, former South Bend, Indiana Mayor Pete Buttigieg and former Vice President Joe Biden - in a statistical tie a few points behind him.
Iowa voters cast ballots in Feb. 3 party caucuses in the first contest in the state-by-state process of selecting a Democratic challenger to Republican President Donald Trump. Thirteen Democrats are still in the race.
The remainder of candidates polled below 10%. Clearing 15% is important in Iowa, a state whose caucus system means supporters of candidates that do not meet a 15% threshold are forced to make a second choice.
The poll still found room for movement among the candidates, though, with 45% of respondents saying they could still change their mind.
