Iowa Democratic Caucus:
The poll asked caucusgoers to name a candidate they have in mind as a second choice. When these are combined with initial preferences, Biden (39%), Warren (34%), Sanders (32%), and Buttigieg (29%) are bunched together. They are trailed by Klobuchar (22%), Steyer (10%), and Yang (7%) as either a first or second choice. These numbers have not changed much since earlier this month.
A key factor in how these second choices will play out, though, is determined by whose supporters will need to realign if their first choice does not reach the 15% viability threshold for convention delegates. If Klobuchar and Yang remain viable in some precincts, the race remains tight. A hypothetical six candidate field puts the race at
Joe Biden 22%
Bernie Sanders 22%
Pete Buttigieg 17%
Elizabeth Warren 16%
Amy Klobuchar 12%
Andrew Yang 05%
Tom Steyer 04%
