The survey released on Monday found that support for the former mayor ticked up from 3 percent to 6 percent among likely Democratic voters and Democratic-leaning independents. 

Sen. Kamala Harris (D-Calif.), meanwhile, fell behind with 2 percent support, a two-point decrease.

This marks the first Hill-HarrisX poll that has been taken since Bloomberg officially jumped into the 2020 race, though he was included as a possible candidate in a previous survey.

Biden still holds the lead, inching up one percentage point to 31 percent support. His fellow top rivals saw a slight dip, with Sanders dropping 3 points to 15 percent support and Warren sliding 5 percentage points to 10 percent.

Buttigieg, who gained momentum in recent weeks, received 9 percent support, a two-point increase from the prior Nov. 16-Nov. 17 poll.

The rest of the contenders in the crowded Democratic field received 1 percent in support or less. Another 3 percent said they were unsure. 

The survey comes in light of an ever-fluid Democratic primary race.

Sestak announced the news in a press release over the weekend, saying he was thankful for what he called an "endeavor filled with immeasurable wisdom, passions, humor and insights to, and from, the people of America."

A day later, Bullock issued a statement announcing his own departure from the 2020 race.

"While the concerns that propelled me to enter in the first place have not changed, I leave this race filled with gratitude and optimism, inspired and energized by the good people I've had the privilege of meeting over the course of the campaign,” he wrote.

The Hill-HarrisX poll surveyed 1,001 registered voters between Nov. 1-Dec. 1. It has a margin of error of plus or minus 3.1 percentage points.
