Just 19 percent of respondents said that Biden had the best chance of beating Trump, a sizable 19-point dip since last month. Eighteen percent of Democratic and Democratic-leaning voters say Bloomberg has the best shot to win the White House. No other candidate received double-digit support in that category.

The ABC News-Washington Post survey falls in line with other polls focused on the Democratic race. An NPR–PBS NewsHour–Marist poll released on Tuesday found Sanders with a 12-point lead over the field.

His rise has coincided with a similar upward climb from Bloomberg, the billionaire businessman who is pouring hundreds of millions of dollars into his campaign. Several Democratic candidates have criticized Bloomberg's presidential bid.

The ABC News-Washington Post survey was conducted among a random national sample of 1,066 adults between Feb. 14 and Feb. 17. It has a margin of error of 3.5 percentage points.
