Lots of crosstalk in this debate so far, and Burgum continues to refuse to be left behind. He just talked over the moderators as they tried to move on to immigration in order to make a point about child care in North Dakota.

Inflation has cooled a lot compared to its highs last summer, at 3.7 percent more than last year as of August. Republican candidates are blaming government spending for inflation, but economists think the pandemic-era inflation was caused more by supply-chain problems caused by the pandemic and shifts in demand because people's needs changed.

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.

At several points during the second hour of the debate, it got particularly heated between former South Carolina Gov. Nikki Haley and someone she appointed to the U.S. Senate in 2013: Tim Scott.

Haley first went after Scott for not completing what he touted as his economic policy accomplishments.

“I appreciate him. We've known each other a long time. But he's been there 12 years and he hasn't done any of that. He has, they've only given four audits on time,” she said.

Then came a heated back-and-forth before Haley repeated, “Twelve years, where have you been? ... Bring it, Tim.”

The two also fought over Haley’s gas tax in South Carolina.

“​​I would love to finish my conversation with Nikki as it relates to the job that needs to get done. Nikki offered a 10-cent gas tax increase in South Carolina. Talk about someone who has never seen a federal dollar,” Scott said.

Haley then told Scott to do his homework regarding the spending and gas tax in South Carolina. He responded, “just go to YouTube.”

Haley ended the exchange by telling Scott that he was “scrapping right now” (as in scrambling).

“You are scrapping right now, you are scrapping. You know, I fought taxes, I cut taxes, I took care of South Carolina and you know it.”

They then got into a rift over a set of over $50,000 customized curtains for the State Department in the official residence of the ambassador to the United Nations. Haley was the first to live in the new residence.
