Poll: Biden leads Dems by 11 points in Iowa

Former Vice President Joe Biden leads the field of potential Democratic presidential candidates by double digits among likely Iowa caucusgoers, according to a new poll. 

An Emerson College poll published Saturday found that Biden has the support of 29 percent of the planned caucusgoers surveyed, well ahead of Sen. Kamala Harris (D-Calif.), who has the backing of 18 percent of likely caucusgoers polled.

The poll was based on interviews with 260 likely caucusgoers and has a margin of error of plus or minus 6 percentage points. The interviews were conducted Jan. 30-Feb. 2.

Following Biden and Harris in the poll is Sen. Bernie Sanders (I-Vt.) with 15 percent and Sen. Elizabeth Warren (D-Mass.) with 11 percent. No other candidate received more than 6 percent of support.

Sanders, who ran against Hillary Clinton in the 2016 Democratic Primary, also has not yet announced a White House bid.

Harris announced last month that she is running for the Democratic nomination, while Warren launched an exploratory committee in December and is expected to soon formally launch her campaign.

The Emerson College poll also found that Biden is the only Democratic front-runner who would defeat President Trump in a head-to-head match-up among Iowa voters. 

The poll shows 51 percent of respondents backing Biden and 49 percent supporting Trump.

That subset of the poll was based on interviews with 831 registered voters Jan. 30-Feb. 2 and has a margin of error of plus or minus 3.4 percentage points.
