Biden has struggled to build enthusiasm among young voters, and some Democrats have expressed concerns about what they see as the campaign's lack of outreach to Latino voters, which Sanders echoed on MSNBC.
How do we get them to vote?”A Biden campaign adviser, Symone Sanders, was asked Sunday on ABC's “This Week” whether the campaign would take Sanders' advice.
“The enthusiasm is with Trump, not with Biden,” Sanders said.
The Biden campaign has focused much of its early efforts on those three states, with Biden and running mate Kamala Harris visiting all three in recent weeks.
While Sanders made his concerns public in recent interviews, he also has expressed them in private to the Biden campaign, according to Faiz Shakir, Sanders’ former presidential campaign manager.
