Former Secretary of State Hillary Clinton has a decisive 22-point lead in the race for the Democratic primary, according to an ABC/Washington Post national poll released Wednesday.

The poll found support for Clinton at 57 percent, while her closest rival, Sen. Bernie Sanders (I-VT), lagged behind at 35 percent. Former Maryland Gov. Martin O’Malley (D) came in at 3 percent.

Although the gap between Clinton and Sanders has narrowed since the same poll was conducted in December, when Clinton led by 59 percent to Sanders’ 27 percent, the poll indicates that Clinton nevertheless continues to hold a clear lead in the national race. Sanders seems to hold the advantage in the early-voting states of Iowa and New Hampshire, though, according to most polling.

The ABC/Washington Post poll was conducted Jan. 21-24 and surveyed 481 likely Democratic voters by live phone interview. It had a margin of error of 5 percentage points.
