Well-off white people with a college degree living in the suburbs really like the Pete.
He's got the more moderate of that group while Warren has the more liberal of them, but they both share very similar demographic support. It's why there are so many Warren and Buttigieg supporters with the other as their second choice. Even on here, I can name three people right away that have them as their top 2.
I've been saying this for ages: The single largest voting bloc in the Democratic primary are swing voters between virtually all of the non-Biden/Sanders candidates (excluding the niche candidates like Yang and Gabbard). Most such voters have supported at least two of those candidates at different points in the primary, some of them three or even four different candidates and former candidates among Warren, Buttigieg, Harris, O'Rourke, Booker, Gillibrand, Klobuchar, etc. Ultimately, the winner of the primary will most likely be the candidate who consolidates those voters. Warren is probably best positioned to do so, but maybe Buttigieg will manage it. Harris, Booker and Klobuchar are probably out of the running to do so at this point. Steyer and Castro are also fishing in the same pool of voters.
