Not boding well for Uncle Joe.
Massachusetts Sen. Elizabeth Warren has overtaken former Vice President Joe Biden in Iowa, according to a new Des Moines Register/CNN poll of the crucial state.
The poll out Saturday night found Warren was the top choice for the Democratic nomination with 22 percent support among likely caucus-goers, while Biden had the support of 20 percent of respondents. Vermont Sen. Bernie Sanders fell to third with 11 percent.
The poll was conducted of 602 likely Democratic caucus-goers from Sept. 14-18. The margin of error is plus or minus 4 percentage points.
The last Register/CNN poll, in June, had Biden leading with 24 percent and Warren in the third spot at 15 percent, slightly behind Bernie Sanders, who came in second with 16 percent support.
