More than half of likely Iowa Republican caucus attendees said they have not made up their minds on a 2024 candidate, a new poll found.

Fifty-two percent of likely GOP caucusgoers in Iowa said they have yet to decide whom to support and that they could be convinced to support another candidate, according to the NBC News/Des Moines Register/Mediacom poll released early Monday.

The results come as many GOP presidential hopefuls have flocked to the state to make their case to Iowa voters, with many hoping to upend former President Trump’s comfortable lead in the polls. They also come ahead of the first 2024 Republican primary debate on Wednesday, which Trump said he is not attending, mainly due to his large lead in the polls.

The new poll found 42 percent of likely Republican caucus attendees in Iowa listed Trump as their first choice, giving the former president a 23-point lead over Florida Gov. Ron DeSantis, who was picked by 19 percent. No other candidate received more than 10 percent of the vote.

Former New Jersey Gov. Chris Christie received 5 percent support, entrepreneur Vivek Ramaswamy received 4 percent, North Dakota Gov. Doug Burgum received 2 percent and former Rep. Will Hurd (Texas) received 1 percent.

The poll was conducted between Aug. 13-17 among 406 Iowa voters likely to attend the 2024 Republican caucus and has a margin of error of 4.9 percentage points.
