Kamala Harris is trailing considerably in her home state, well behind front-runners Joe Biden, Bernie Sanders, and Elizabeth Warren and even lagging long-shot hopeful Andrew Yang, according a poll of California Democratic voters released Tuesday.

A survey by Emerson Polling found Biden and Sanders tied for first, with both receiving 26% support. Warren placed third with 20%.

Democratic primary voters gave fourth place to tech entrepreneur Yang, with 7% support, while Harris is in fifth at 6%.

The rest of the field was also far behind the leaders. Former Texas Rep. Beto O'Rourke placed at 5% and South Bend, Indiana, Mayor Pete Buttigieg at 4%. The rest of the field polled at 2% or less.

"Senator Kamala Harris is in trouble in her home state. If she is unable to gain momentum in Iowa or New Hampshire, come Super Tuesday she might have a similar fate to Sen. Marco Rubio in 2016, when he was unable to win his home state of Florida and dropped out of the race,” said Emerson Polling Director Spencer Kimball.

Harris has consistently struggled to gain momentum for her candidacy despite a strong performance at times during Democratic debates. A RealClearPolitics average of national polls of Democrats have her placed in fourth place at 6.2%, more than 10 points behind Sanders, who is in third.
