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.

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.
