Sanders Leads the Iowa Primary, Followed by Buttigieg, Biden, and Warren
Sanders has the support of 27% of likely caucusgoers; Buttigieg and Biden trail him with 19% and 18%, respectively; Warren is next with 15%; and Klobuchar is at 10%. Other than Yang and Steyer, at 4% each, no other candidate is above 1%.
However, many voters are still unsure. 48% of caucusgoers say they could still change their mind. Furthermore, 52% either have made up their mind in the last month or haven’t made up their mind at all. Sanders’s support is firmest: 65% of Sanders voters say they’re absolutely certain to stick with him. Warren is next on this measure, at 58%, while Buttigieg is at 53%. Only 49% of Biden’s supporters say they’re certain to caucus for him, and Klobuchar’s number is only 35%.
Of the voters who’ve made up their minds in the last week, 25% have gone with Klobuchar, suggesting she may have some momentum. Next up among that cohort of voters are Warren at 17% and Buttigieg at 16%. Among those who say they’re still making up their mind, Biden (22%) and Klobuchar (21%) lead.
No candidate is poised to gain disproportionately from attracting nonviable candidates’ supporters. Warren is the most voters’ 2nd choice, but only because she’s the most Sanders voters’ 2nd choice — and Sanders will likely be viable in most precincts. Buttigieg, Biden, and Warren are all poised to pick off a significant number of Klobuchar supporters in places where Klobuchar isn’t viable; the other candidates’ supporters fan out to the top five candidates. We see this when we ask which of the top 4 candidates voters would support if they had to choose: the margins are almost identical to how they look in the initial toplines, with Sanders at 30, Buttigieg at 23, Biden at 22, and Warren at 20. 5% say they’re not sure.
Sanders Leads Among All Voter Groups Besides 65+
Sanders has the support of 46% of caucusgoers between 18 and 34 (Buttigieg is next with 17%) and 38% of those 35-49 (Warren is next with 19%). Sanders’ lead narrows among those between 50 and 64. Voters 65 and older are closely divided: Biden has 24% of their support, while Buttigieg gets 21%, Klobuchar 20%, Sanders 15%, and Warren 13%. We estimated, based on voting history and voters’ self-stated likelihood of caucusing, that 18% of caucusgoers will be under 35, and 38% under 50. If these groups turn out at higher numbers — which is within the realm of possibility — Sanders could win by a wide margin.
What Voters are Looking for in the Democratic Nominee
29% picked their candidate because they thought they’d have the best chance to beat Trump, while 71% based their choice on who they thought would be the best President. But the differences among candidates is striking: 49% of Biden supporters chose him because they thought he’d win in November, along with 42% of Klobuchar supporters. Among Buttigieg, Sanders and Warren voters, the numbers were 22%, 20%, and 13%. We see a similar pattern when we ask voters to choose between “major change” and “getting rid of Trump.”
