The New York Times reports:
Senator Bernie Sanders has opened up a lead in Iowa just over a week before the Democratic caucuses, consolidating support from liberals and benefiting from divisions among more moderate presidential candidates who are clustered behind him, according to a New York Times/Siena College poll of likely caucusgoers.
Mr. Sanders has gained six points since the last Times-Siena survey, in late October, and is now capturing 25 percent of the vote in Iowa. Pete Buttigieg, the former mayor of South Bend, Ind., and former Vice President Joseph R. Biden Jr. have remained stagnant since the fall, with Mr. Buttigieg capturing 18 percent and Mr. Biden 17 percent.
IOWA BERNING @BernieSanders takes lead outside margin, consolidating left and taking advantage of moderate divisions
And when the field is narrowed to top four, he’s….still up
