A survey from Emerson Polling released Thursday found the top two candidates tied at 23 percent each among voters who are expected to participate in the first caucus of the 2020 primary.

The results underscore Warren's rise in the primary race, and compares with previous Emerson Polling data released in March that showed Biden with a 16-point lead over the senator in Iowa.

Warren's support in the Hawkeye State has increased by 14 points compared to the survey conducted earlier this year, while Biden's support has dropped 2 points.
