Moderator Dana Perino asked every candidate to write down which challenger they would “vote off the island.” DeSantis refused, prompting Perino to rework her approach, asking for his mathematical approach to winning the nomination — and of course, that’s not going to work with a politician. Christie, however, interjected that he’d be just fine voting Trump off the island.

DeSantis claimed that his 1.5 million-vote victory was the largest in a Florida gubernatorial election in state history. Now, his nearly-20 percentage point margin of victory was quite large in what has historically been a swing state. But it's quite misleading to use the raw vote margin since population has changed quite a bit over time! This is especially true in a state like Florida, which has grown by leaps and bounds. For instance, a candidate would've had a tougher time winning by 1.5 million votes in 1990, when the state had a population of about 13 million, than in 2022, when the state had a population of about 22 million.

After mixing it up with her earlier, Scott goes out of his way to attack Haley again. He very much wants to be in her position — rising in the national polls, in second place in New Hampshire in some polls — right now.

Pence and Trump keep trying to claim they passed the largest tax cuts in American history as if one time it might be true.

It is not.

In inflation-adjusted dollars, the 2017 tax bill is the fourth-largest since 1940. And as a percentage of GDP, it ranks seventh.

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.
