For the first time in the 2020 Democratic primary, a major state poll showed Joe Biden losing his lead in Iowa as the Des Moines Register released a survey showing Sen. Elizabeth Warren with more support than the former Vice President.

The Massachusetts senator was supported by 22 percent of likely caucus-goers in the Des Moines Register/CNN survey, which was conducted between September 14th and 18th and released Saturday evening.

Biden had the support of 20 percent of respondents while Sen. Bernie Sanders (I-Vt.) was backed by 11 percent.

Warren’s support jumped by seven percentage points since the newspaper last conducted a poll, while Biden’s fell by four percentage points.

Twenty percent of respondents also named Warren as their second choice and 29 percent said they were considering voting for her.
