None of the remaining candidates polled broke double digits.

The poll is the latest in Iowa to show a lead for Warren, who has recently ranked at the top in several other national and early-state surveys.

Warren leads in every voting demographic except independents and voters aged 18-34, who back Sanders by 9- and 6-point margins, respectively.

The poll is also welcome news for Buttigieg, who has worked to cast himself to centrist voters as an alternative to Biden. The Indiana Democrat saw a surge in donations and attention after last week’s debate in which he hammered Warren over her “Medicare for All” platform after she ducked questions about whether she would raise taxes on middle class families.

Buttigieg also holds a slim 19 percent to 18 percent advantage over Warren among independents.

The Iowa poll comes as other surveys show Biden's overall lead in the 2020 race has narrowed, as measured in the RealClearPolitics polling index, though he still has strong support in other polls, including a CNN poll released Wednesday that showed him with a double-digit lead in the primary field.

The Civiqs poll surveyed 598 likely Democratic caucus attendees from Oct. 18-22 and has a margin of error of 5 percent.
