Adding onto Nathaniel's Google search comment ... debates can serve as a great introduction to some of the lesser-known candidates. Ramaswamy is probably tonight’s big winner in making a name for himself: 59 percent of voters had no opinion or had never heard of Ramaswamy before tonight, according to a favorability question in our pre-debate FiveThirtyEight/Washington Post/Ipsos poll. That’s likely changed after all of the talking he’s done on stage — and we’ll be tracking whether that’s a good or bad thing. Check back in at FiveThirtyEight tomorrow afternoon for our post-debate analysis.

Pence was pressed by moderators if presidents should have to pass a mental and physical test to serve, invoking President Joe Biden's age.

Pence, who is 64, initially joked that "it might be a good idea to have everybody in Washington" pass one.

He then took a serious tone, saying, "No, the American people can make those judgments."

He appeared to take a swipe at Ramaswamy, the youngest candidate on stage, stating the nation doesn't need a president who is too young either.

In the front-runner's absence, many of us here at FiveThirtyEight suspected (in part because of some leaked debate memos) that the former president would loom large over the proceedings, with candidates taking shots at him whenever possible. That hasn't really happened tonight, though! What do you make of it?

Ramaswamy has been far and away the most Googled candidate during the debate tonight. He’s received three times as much search interest as DeSantis or Haley. Now, I’m not sure what that means for his chances — Google searches aren’t votes, and people might just be curious to learn more about him. But I think it does reflect that he has been the story of this debate so far. Whether that’s a good story for him or a bad story is still TBD.

Tonight I’m on Pence and Hutchinson duty. Neither candidate appears to have a great shot at winning the primary — the former vice president is at 4 percent in FiveThirtyEight’s national polling average while the former Arkansas governor hasn’t even garnered 1 percent — but Pence at least has a decent chance of making a debate-night splash. Given the events of Jan. 6, 2021, Pence has the strongest claim to the anti-Trump “lane” of the primary. I wouldn’t be surprised if we saw some real fireworks between him and the GOP candidates who have been quick to jump to Trump’s defense after the bad news he has been hit with over the past year. For his part, Hutchinson will have to pull off a masterclass in persuasion and performance to gain substantial ground. In our poll with Ipsos and The Washington Post, only 6 percent of Republicans said they were even considering voting for him, much less were intending to do so. In a more fluid primary, he’d maybe have a shot at doing something about that. But with Trump as the default and other candidates leading the various anti-Trump lanes, those are really tough numbers to come back from.
