The data for this claim is incomplete. Crime figures are low in Florida, but DeSantis’ figure comes from a database containing information from law enforcement agencies that represent only around 57 percent of the state’s population, a Sept. 20 NBC News report found.

The patchy data is related to Florida’s transition to incident-based crime reporting, the new federal standard, rather than the summary-based reports it has used since the 1970s. With summary reporting, if one incident resulted in multiple crimes, only the most serious would be reported. In 2021, the federal government stopped accepting this type of data, and now requires states to report each crime.

FBI’s crime reporting database doesn’t support DeSantis’ figure either. Only 48 out of 757 Florida law enforcement agencies participated in the FBI’s data collection in 2021. The numbers appear to be similar for 2022, according to a Marshall Project analysis.

Haley was just asked about hiring more police officers. According to a May poll conducted by Ipsos for Reuters, 91 percent of Republicans said they were more likely to support a presidential candidate in 2024 who “supports increasing police funding to fight crime.” 53 percent said they were much more likely, while 38 percent said they were somewhat more likely. Just 9 percent said they were less likely to vote for such a candidate.

This is False.

Pence has used this 90 percent drop statistic many times, but has never explained where it comes from.

When the COVID-19 pandemic started, immigration drastically dropped worldwide as governments enacted policies limiting people’s movement. In the U.S., Trump instituted Title 42, a public health policy that authorized the Border Patrol to immediately return most immigrants back to Mexico. The increased use of this policy decreased the use of other programs, including "Remain in Mexico."

U.S. Customs and Border Protection during the pandemic also adopted a new way of reporting migrant encounters. Before the pandemic, it only reported enforcement actions under immigration law; its data during the pandemic includes actions taken under both immigration law and the public health policy. Therefore, 2020 data isn’t entirely comparable to pre-pandemic numbers.

Accounting for challenges in data comparisons, our review found an increase of 300 percent in illegal immigration from Trump’s first full month in office, February 2017, to his last full month, December 2020.

One way to get close to Pence’s alleged 90 percent decrease in illegal immigration is by comparing data from May 2019, the month during the administration that had the highest apprehensions, to April 2020, the month with the lowest enforcement actions in calendar year 2020.

But that’s a severely cherry-picked time period.

In anticipation of tonight’s debate, we again partnered with The Washington Post and Ipsos to ask likely Republican primary voters what they think about tonight’s debate participants and the candidate field in general.

The 5,002 likely Republican primary voters we polled using Ipsos’s KnowledgePanel expect DeSantis and Ramaswamy to perform best, out of the seven-candidate field. According to a five-point scale that we calculated using respondents’ answers (with 1 being “terrible” and 5 being “excellent”), likely voters expected both DeSantis and Ramaswamy to perform “very good” (3.44 and 3.43 out of 5, respectively). They thought Haley would perform third-best (3.40 out of 5) and Scott fourth (3.20 out of 5). All of this is fairly in line with their pre-debate expectations in August.

When it comes to which candidates respondents are interested in, Haley saw the biggest bump since our poll before last month’s debate — 31 percent are now considering voting for Haley, up from 25 percent. Although she now has the third-most prospective support, she’s still got a long way to go compared to Trump (66 percent) and DeSantis (49 percent). About 1 in 4 likely Republican primary voters are also considering voting for Ramaswamy and Pence.

We’ll be watching to see how the candidates fare tonight, and if debate watchers’ opinions on who they’re considering voting for will change after tonight’s performances.
