Kamala HarrisKamala Devi HarrisGOP rep to introduce constitutional amendment to limit Supreme Court seats to 9 CNN to host town hall with Cory Booker in South Carolina O'Rourke sees 'a lot of wisdom' in abolishing Electoral College MORE (D-Calif.) has jumped in the polls since she joining the crowded 2020 field of Democratic presidential hopefuls, Morning Consult reporter Eli Yokley said Friday on Hill.TV.

"I think what's been notable is the rise of Kamala Harris," Yokley told Hill.TV's Krystal Ball on "What America's Thinking."

"Since she announced, she has seen a big rise among the candidates who have declared," he added.

A Morning Consult poll released this week found that 13 percent of Democratic primary voters favored Harris, who announced her candidacy in January.

Since then she has seen a rise in the polls and took part in a prime time CNN town hall that drew high ratings.

"What's going to be really interesting to us is when Joe Biden and Bernie Sanders end up making a decision, because as those second choice questions show you, a lot of folks have them on their minds regardless of who they support," Yokley said. "So I think in the minds of a lot of Democratic voters, they need to decide before they can decide on the other candidates in the race."
