The poll suggests Biden and Sanders are reaping the benefits of being better known by locking in their supporters early. Among those who say they have made up their minds, Biden’s support rises to 43%, Sanders climbs to 29%.
Both also have overwhelmingly positive favorability ratings among potential Democratic voters. About three-quarters say they have a positive view of each (77% for Biden and 76% for Sanders), well ahead of their closest competitors for the nomination (Harris is viewed positively by 52% of Democratic-leaning voters, Warren 63%).
Among all Americans, however, Biden fares better than Sanders. The former Delaware senator earns a significantly positive favorability rating nationally (46% favorable to 38% unfavorable). Views on Sanders are almost evenly divided, and tilt positive by just two points (46% favorable to 44% unfavorable).
