Since the May Emerson Iowa poll, Biden’s support has decreased 19 points in the Democratic Caucus, from 69% to 50%

Since the May Emerson Iowa poll, Trump’s support has decreased 13 points, from 62% to 49%

“Biden has lost some support in the Democratic caucus, with a large number of voters being undecided,” Kimball said. “Young voters and women voters are two groups who have lower support for Biden than their counterparts: only 38% of Democratic voters under 30 support Biden in a caucus, and 41% of women are undecided.

“While both Biden and Trump have lost some support in Iowa, it does not appear that any other candidate has been able to emerge as a clear alternative. Republicans saw DeSantis fall back into the pack, as the vote splintered amongst a crowded field, and Kennedy and Williamson have failed to gain traction in Iowa.”
