"I do think for Kamala Harris in particular, there's a potential upside because, among Democrats, she is really well-liked," Newall, research director at Ipsos Public Affairs, told Hill.TV's Jamal Simmons on "What America's Thinking."

MORE, who has yet to launch a 2020 bid, have continuously been the best-known candidates in the field, according to various polls.

"So I think there's a potential upside for her to exist in this space of ... going back to the idea of being a change agent, a woman of color who is progressive on a number of issues, and who is kind of looking to shake up the status quo," she said.

A Des Moines Register–CNN–Mediacom Iowa poll released earlier this week found that 27 percent of likely Iowa caucusgoers said Biden is their first choice for president, followed by Sanders, at 25 percent.
