Buttigieg has gained ground among every major demographic group since the summer. His support stands at 26% among voters who describe themselves as moderate or conservative, 23% among those who are somewhat liberal, and 15% among those who are very liberal. He is currently in the top tier for both women (24%, to 22% for Biden, and 20% for Warren), and men (20%, to 19% for Sanders and 16% for Warren). Looking at the poll results by age, Buttigieg (26%) is nipping at Biden’s heels (29%) among voters age 65 and older. He has a slight advantage among those age 50 to 64 (24%, to 17% each for Biden and Warren), and is competitive among voters under the age of 50 (19%, to 24% for Warren and 19% for Sanders). Buttigieg leads among college graduates (24%, to 21% for Warren and 15% for Biden) and is in the top tier among those without a college degree (21%, to 21% for Biden, 18% for Sanders, and 16% for Warren).

“Buttigieg is emerging as a top pick for a wide variety of Iowa Democrats. While he has made nominally bigger gains among older caucusgoers, you really can’t pigeonhole his support to one particular group. He is doing well with voters regardless of education or ideology,” said Patrick Murray, director of the independent Monmouth University Polling Institute.
