Christie gets the first question out of the break on how to handle crime, and he made the case that he's the only person on stage whose done it as a former prosecutor. But he turned the question into an attack on Trump, calling out Trump for skipping out on the debate, saying that soon he'll be called "Donald Duck" for avoiding it. The thing is, Christie has essentially a 0 percent chance of winning the GOP nomination, so it's not especially interesting to hear him go after Trump. Earlier in the debate, DeSantis did echo an attack Christie made by hitting Trump for not being on stage to defend the former president's record on spending. More of those kind of dings from anyone besides Christie would be a development in this debate.

DeSantis stands by his decision to suspend two elected prosecutors in Florida, and says he'll bring civil rights cases (?) against local prosecutors as president.

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 was a weird debate, full of interruptions and crosstalk. I'm skeptical anyone actually "broke through" in some huge, game-changing way, and neither of the candidates I closely monitored — Haley or Christie — looked likely to suddenly gain 10 points in the polls next week.

But I did think Haley mostly had a strong night, building on her well-received showing in the first debate. She made the case for a more restrictive approach to border security, dinged Biden for his handling of the economy and immigration, and argued that TikTok is a huge danger to the country. That said, I do wonder if she might've rubbed some viewers the wrong way by saying she felt dumber after listening to Ramaswamy, and with her interruption-filled argument with Scott late in the debate. I say that because of how women are sometimes perceived in those sorts of situations — female candidates in the past have been tagged with misogynistic descriptors like "shrill," for instance. I look forward to seeing the post-debate 538/Washington Post/Ipsos poll to get a better read on how she came across.

As for Christie, he continued to be the one person in the room unafraid of attacking Trump, doing it on a good share of his answers. On the one hand, he's got nothing to lose as the GOP candidate with the worst favorability rating among Republican voters. On the other hand, his dings did occasionally free up opportunities for other candidates to make small digs at Trump without going after the former president as aggressively as Christie did. (For instance, DeSantis took a shot at Trump for adding significantly to the national debt after Christie brought it up.) Christie probably knows that he's got no chance of winning the GOP nomination, but he may also be thinking strategically about how he can help his party avoid renominating Trump. Still, it's going to take some pretty drastic changes in the race for that outcome — Trump winning the GOP primary — to not come to pass.
