CBS News Battleground Tracker poll: Biden leads, with Warren, Harris, Sanders close behind

1. The paragraph about first-choice vote is most crucial here:

Biden is the most effective at translating consideration into a first-choice vote. He leads across the early states in vote preference with 31% of Democratic primary voters, compared to Warren's 17%, Sanders' 16%, and Harris' 10%. Biden converts most of those considering him into picking him as their first choice when pressed, but fewer of those considering Warren or Sanders — roughly a third – pick those candidates as their first choice.

Editing to add that the article goes on to note that if these first-choice picks are translated to primary wins, that would mean 731 delegates for Biden, compared to 355 for Warren and 317 for Sanders.
