Despite DeSantis’s strong words against Trump, likely Republican primary voters still think highly of Trump, according to our pre-debate 538/Washington Post/Ipsos poll. 68 percent view Trump favorably, compared to 30 percent who have an unfavorable view.

Government spending is certainly a factor when it comes to inflation. But it’s not the only factor.

The 2021 American Rescue Plan Act added about $1.9 trillion to the economy, and economists across the political spectrum say that it spurred inflation. They differ on the precise scale of its impact, with estimates ranging from two to four additional points out of the current inflation rate of about 8.5 percent.

However, none of the experts PolitiFact talked to, liberal or conservative, said Biden’s actions were responsible for all of the inflation. Past government spending, COVID’s disruptions to labor markets, energy prices and supply-chains also played significant roles. Most recently, the war in Ukraine has made a challenging situation worse.

It took 15 minutes for the putative polling front-runner to get a word in, and DeSantis uses it to go after Trump on the debt and not showing up for the debate tonight. He even brought a prop -- a veto pen that he says he'll use to block "bloated spending" bills as president. But if he only gets off a few words every 15 minutes, this will be a long night for him.

Christie goes after Republicans and Democrats for adding billions to the D.C., but he also takes a shot at Trump for not showing up to the debate. This is the first mention of the former president who is very likely to defeat all of these Republicans in the GOP primary.

Foreign policy isn’t quite dominating this debate, but U.S. policy towards China is a prominent theme, and Ramaswamy is bearing down a lot of attacks on that.

Ramaswamy and Haley had a heated moment on the debate stage over the issue of support for Ukraine – which Haley tied to China. When Ramaswamy argued against support for Ukraine, Haley jumped in, saying that a win for Russia is a win for China, and then accused Ramaswamy of liking China.

There was also the memorable TikTok exchange between the two. Haley sniped at Ramaswamy that "every time I hear you, I feel a little bit dumber for what you say” and that he can't be trusted as he justified his choice to join TikTok after being convinced by influencer and boxer Jake Paul to join despite previously calling it "digital fentanyl." TikTok was created by Chinese company ByteDance and lawmakers have scrutinized the app over security concerns. (Ads for TikTok are also airing on Fox Business Network during commercial breaks.)

Scott also accused Ramaswamy of being ‘bought’ by China. He was likely referencing Ramaswamy's company, Roivant Sciences, announcing 5-years ago that it was partnering with China state-owned investment company CITIC Group Corp

And Pence had a similar, pointed attack: “I'm glad Vivek pulled out of his business deal in 2018 in China -- that must have been about the time you decided to start voting in presidential elections."

It’s worth noting that Haley criticized Trump too on this front, in that case for not pursuing China aggressively enough on a host of issues: “This is where President Trump went wrong.”
