“Oh, yes,” the California Democrat told CNN Thursday when asked if she thought Biden would run, though she clarified that he did not definitively tell her either way.

Sources familiar with Biden’s plans also told The Hill that he is almost certain to jump into the race and has been calling on party donors for help leading up to his campaign announcement.

Whether or not Biden will throw his hat into the ring has been one of the largest questions looming over a Democratic primary field that already includes high-profile candidates including Sens.

Some analysts told The Hill that Biden would likely angle his campaign’s appeal toward blue-collar workers in the Rust Belt and a more traditional Democratic base over the progressive voters whose support several other candidates are trying to win. He’s remained popular among Democrats since his time in the Obama White House and consistently performs well in national and statewide polls.

Feinstein said she would likely support Biden, possibly over fellow Californian Harris.

“He made me the first woman on the Judiciary Committee 26 years ago, and I’ve never forgotten it,” Feinstein said, referring to Biden’s tenure leading the panel. “I’ve known him, I’ve worked with him and it’s just a logical step for me.”
