A new poll showed that 15% of Sen. Bernie Sanders’s supporters are likely to vote for President Donald Trump in the November election if former Vice President Joe Biden becomes the Democratic presidential nominee.

The ABC News/Washington Post poll also showed that 80% of Sanders’s backers said they would support Biden over Trump.

The poll came as Biden holds a more than 300-delegate lead over Sanders, and therefore will have better chance to secure the party’s presidential nomination.

If the poll is accurate, there will be a slightly larger defection than occurred after the bitter battle between Sanders and former Secretary of State Hillary Clinton in 2016, when 12% of Sanders voters broke for Trump in the general election, according to USA Today.

The 15% who are likely to vote for Trump represent 6% of all leaned Democrats, and Trump won 8% of Democrats in 2016. Still, Biden wants all the in-party support he can muster.

The poll showed that supporter enthusiasm for Biden is lower than Trump. Among Trump’s backers, 53% said they would be “very enthusiastic” to cast their votes for him, while 24% of Biden’s supporters said the same for their candidate.

That is the lowest for any Democratic presidential candidate in 20 years in an ABC/Post poll.

Among Sanders supporters who said they back Biden in November, just 9% said they were very enthusiastic about doing so. 

When it came to the economy, Trump also held an edge over Biden where 57% said they approved of the president’s performance. When asked who they would trust more to handle economic matters, 50% said Trump and 42% said Biden. 

In handling the CCP Virus  outbreak, Trump also narrowly bested Biden on the issue, with 45% of Americans saying they trusted Trump more to deal with the crisis, while 43% saying they had more faith in Biden.

When it came to health care, however, Biden was more trusted by a wide margin of Americans (52%-39%) over Trump. 

The poll, conducted from March 22 to March 25, came as other surveys have also shown a rise in Trump’s approval rating amid the battle against the CCP Virus.
