No other candidate even came close Biden's number when voters were asked if they thought each individual candidate could win against Trump. Almost four-in-ten (38%) Democrats and Democratic-leaning independent voters said they'll support Biden in the primary from the new poll. He still has the plurality of the group, but the difference on the issue is 15 percentage points, a substantial decrease. Meanwhile, both Warren and Sanders have a significant increase when it comes to policy -- Warren up seven percentage points and Sanders up five. Results for the full sample have a margin of sampling error of plus or minus 3.8 percentage points.
