The online survey by YouGov was sponsored by MoveOn.org and Democracy for America, which have staff and offices in Iowa and New Hampshire working to build support for a Warren candidacy. Its margin of error is 6.7% in Iowa and 6.3% in New Hampshire.

Voters in Iowa favor Warren over Clinton 31% to 24%, although 35% of likely caucusgoers say they are still unsure. In New Hampshire, where Clinton won the Democratic primary in 2008 against Barack Obama, Warren leads Clinton by a smaller margin, 30%-27%, and 31% are unsure.

The poll shows voters in the early states are “moveable,” says Adam Ruben of MoveOn.org. “There’s an opening for her to build the level of support she would need to win.’’

A Bloomberg Politics/St. Anselm College poll released Feb. 8 showed Clinton leading Warren 56% to 15% among likely Democratic primary voters in New Hampshire.

“A candidate like Elizabeth Warren, as these numbers show, is capable of creating lightning in a bottle.’’
