Warren’s not only grown her support since March, but her net favorables have grown, and the number of people who have her as their second choice has grown as well. (They didn’t ask the ‘considering voting for’ question in March, but given how high that is for her…) Other than Buttigieg, she’s the only candidate that this can be said about.
In short, she’s still got a lot of room to increase her support in Iowa over the next 4+ months.
