He currently earns 13% support in the poll, similar to prior results. However, the Monmouth poll finds his support should grow if he chooses to enter the fray. An additional 12% of Democratic voters say they would be very likely to support Biden if he gets into the race and another 31% say they would be somewhat likely. Taken together with the support he currently holds in the vote choice question, about 1-in-4 voters say they would be very likely to get behind Biden, and more than half would be at least somewhat likely. Most of this new support would come at the expense of Hillary Clinton. Among those who say they would be likely to vote for Biden if he runs, 68% are currently Clinton backers, 18% are currently supporting another candidate and 14% are undecided.
