New Jersey U.S. Sen. Cory Booker lost ground among support from Iowa voters – where the second presidential nominating contest will be held after the New Hampshire primary this February – according to a new Monmouth University Poll.
The poll, released Thursday, shows only 1 percent of Iowa voters would choose Booker as of August – down from 3 percent in April – from among the crowded field of 24 candidates eyeing the Democratic nomination to unseat U.S. President Donald Trump.

That leaves Booker tied with Montana Gov. Steve Bullock, U.S. Rep. John Delaney of Maryland, U.S. Rep. Tulsi Gabbard of Hawaii and former Colorado Gov. John Hickenlooper.
Only 4 percent of voters picked Booker as their second choice, compared to 6 percent in April, the poll found.
At the top of the list is former Vice President Joe Biden with a 28 percent approval rating, followed by Massachusetts U.S. Sen. Elizabeth Warren with a 19 percent approval rating, and U.S. California Sen. Kamala Harris with an 11 percent approval rating, according to the poll. Vermont Sen. Bernie Sanders slipped down the leaderboard and now garners a 9 percent approval, compared with 16 percent in April.
Monmouth interviewed 681 Iowa voters between Aug. 1 and 4.
During the July 31 Democratic debate, Booker and Biden had a showdown over race relations, during which the New Jersey senator interrupted the former vice president to say “you’re dipping in the Kool-Aid and you don’t even know the flavor.” The moment led to a brief frenzy on social media for the next day.
