No one knows with any real certainty who will win the 2020 Democratic presidential primary. One decent bet to make is that former Vice President Joe Biden and Vermont Sen. Bernie Sanders are the most likely candidates to hold onto to a firm base of support as we head into the primary season.
Over and over again, Biden and Sanders’ voters say they are the least likely to change their mind. In our latest CNN/SSRS poll, Biden scores 37% among those potential Democratic primary voters who say they are definitely going to vote for the candidate they currently support. That’s well above the 28% he gets overall. Sanders exhibits a similar pattern: He earns 17% overall and 25% among those who say they will definitely vote for the candidate they currently support. CONT.
