Our new CNN/Des Moines Register/Mediacom poll of likely Iowa Democratic caucusgoers shows that Sen. Elizabeth Warren has climbed to 22%. She was at 15% in June.
Former Vice President Joe Biden's at 20%, slightly down from 23% in June.
All other Democratic candidates are well in the back of the pack. These include Sen. Bernie Sanders at 11%, Mayor Pete Buttigieg at 9% and Sen. Kamala Harris at 6%.
Everyone else is below 5%.
Here are a few other takeaways from the poll:
- Warren's jump occurred in-part because she's doing well with both people who caucused for Hillary Clinton in 2016 (22%) and those who caucused for Sanders (32%).
- Warren gets 24% of the vote from the 28% of caucusgoers who are comfortable with “Medicare for All” but think it could cost Democrats the election. Can she keep it up?
- Among those who say they are certain of their vote, it's Biden 26%, Sanders 19% and Warren 14%. This suggests Warren's support is less secure than others.
- Buttigieg has a 33% very favorable rating, which is second highest in the field to Warren's 44%. This could indicate that he has a lot of room to grow.
- A look back at past Iowa caucuses' polling at this point suggests that no candidate has greater than a 30% chance of winning given their current polling.
