The new Des Moines Register/CNN/Mediacom survey of likely Iowa caucusgoers released Saturday shows that although Biden’s support registered at 24 percent — a fall of 3 percentage points from the last poll — he has stretched his lead to 8 percentage points over Sanders, from 2 percentage points in March.

Sanders and Warren registered at 16 percent and 15 percent respectively, with Sanders’ support decreasing by 9 percentage points. Sanders narrowly lost the 2016 Iowa caucuses to Hillary Clinton.

Buttigieg made a strong debut at 14 percent, or 1 percentage point behind Warren. Sen. Kamala Harris remains steady at 7 percent compared with the last Iowa poll. Former Texas Rep. Beto O’Rourke dropped 3 percentage points and is now at 2 percent. Sen. Amy Klobuchar registered at 2 percent, with Sen. Cory Booker at 1 percent.
