Senator and potential Democratic candidate for the US presidency, Bernie Sanders, is showing today an important lead in Iowa according to a new poll released almost a week before the caucus of that state.

The poll, conducted by The New York Times and Siena College, showed that the Vermont legislator is backed by 25 percent of Democrats in that territory, after winning six percentage points in a similar poll in October.

Meanwhile, former Mayor of South Bend, Indiana, Pete Buttigieg, and former Vice President Joe Biden, have remained stuck since the previous poll and appear in second and third place, with 18 and 17 percent, respectively.

When releasing the results of this poll on Saturday, the Times said Sanders consolidated its lead due to the support of the liberals and has benefited from the divisions among the most moderate presidential candidates who come after him.

His rise came at the expense of other progressive potential candidates, for instance, Senator Elizabeth Warren, who fell from 22 percent in the October poll, enough to lead the group then, to 15 percent now.

They are the only candidates with more than 10 percent of the support out of the 12 potential candidates who are seeking the nomination by the party for the presidential elections in November, when current President of the country, Republican Donald Trump, will seek re-election.

Based on the results of this new poll, the Times said that the changing fate of the two liberal candidates, and the second position of the two main moderates, highlight the volatile nature of the Democratic primaries after more than a year of campaigning.

‘At various times during the past six months, Warren and Buttigieg had risen in Iowa, only to fall later, while Biden’s strength decreased and flowed here, even when he remained at the top of the nationwide polls,’ the Times said.

But Sanders, who describes himself as a democratic socialist, seems to be peaking at the right time: this month was the first time that he led a poll in Iowa, after leading the Des Moines Register and CNN polls two weeks ago.

Despite his progress, 55 percent of respondents answered that they preferred a more moderate candidate than most Democrats, and only 39 percent supported a more liberal one.

The Iowa caucuses, to be held on February 3, are very important in the fight for the nomination of this party because the process of primary elections begins with them.
