As the debate got underway, Burgum was seen standing without his crutches on the presidential primary stage. Just one day ago, on Tuesday, the North Dakota governor tore his Achilles tendon and was seen just hours ago using crutches.

Christie just made an electability argument — that he was elected as a Republican in the blue state of New Jersey. (Specifically, he won the 2009 gubernatorial election by 4 percentage points a year after Obama won the state by 16.) The only problem is, only 25 percent of Republicans said the ability to beat Biden was one of the most important factors to their vote, according to a recent FiveThirtyEight/Washington Post/Ipsos poll.

Tim Scott was just asked about government spending. In a March poll by AP-NORC, 88 percent of Republicans said that the federal government is spending too much. However, in the same survey, a majority of Republicans thought the government was spending too little on some key areas, including border security (85 percent), law enforcement (67 percent), infrastructure (61 percent), Social Security (57 percent), military (57 percent) and education (52 percent).

I wrote about this earlier, but high consumer prices are probably the biggest way that Americans understand the economy. Biden's trying to make the case that overall the economy is on the upswing, and he has some data points to back him up. And there's not a lot the president can do about inflation. But voters have been sour on the economy since Biden took office. Fifty-three percent of Republican voters said getting prices under control was a top issue in a FiveThirtyEight/Washington Post/Ipsos poll released today.

As Republican candidates gear up for the debate, many have specific rituals they’ll be doing in preparation.

A campaign adviser for Haley said she will be listening to music, “lots and lots of music: Joan Jett, Queen, Def Leppard and [the] Go-Gos, to name a few.”

DeSantis has spent today with his wife, Casey, and their three children, though a campaign spokesman offered few details about how the family has spent their time.

Hutchinson posted a photo of himself preparing with notepad and laptop in hand.

“Some last minute studying and prep for tomorrow! It’s important to show up and be ready to answer the tough questions, you deserve nothing less than a leader ready to lead on day one,” Hutchinson captioned the photo online.

Pence will plan to spend time in prayer before the debate, while Scott took a tour of the debate stage, which he posted a video of, along with encouragements from his family, to X, formerly known as Twitter.

Others prepared physically, earlier this week.

Ramaswamy posted videos to X of himself playing tennis and him and his wife doing floor exercises in a gym throughout the lead-up week.

Burgum was playing a stress-relieving pickup game of basketball on the eve of the debate, according to a campaign press secretary, when he sustained an Achilles injury that called into question his ability to participate in the event.

He will be participating, albeit on crutches, per a photo posted to his X account.
