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.

Several of the Republicans on stage touted their prioritization of border security should they win the presidency.

“What I’ll do on day one is sign an executive order to send the National Guard to partner with Customs and Border Patrol to make sure that we stop the flow of fentanyl over the border,” Christie said first. He expanded his answer to include his plans to fill the “6 million vacant jobs” in the country with legal immigrants.

“This border is going to be a day one issue for me as president,” DeSantis said, also noting that he’d administer the remain in Mexico policy, which requires migrants seeking asylum to remain in Mexico until their US immigration court date.

“We're going to declare a national emergency. Yes, we'll build the wall. We’ll do remain in Mexico,” DeSantis said.

Pence spoke about his role in negotiating the remain in Mexico policy of the Trump administration.

“I negotiated the remain in Mexico policy with the Mexican government. We used economic power to bring the Mexican government to the table. We build hundreds of miles of border wall and despite what's said here today, we reduced illegal immigration and asylum abuse by 90%. And as President of the United States, I can do it again,” he said. “I'm going to be ready on day one to get Congress to step up, secure the southern border of the United States.”

Haley cosigned on the Remain in Mexico Policy.

“Let's go back to Remain in Mexico policy,” she said. “Instead of catch and release. Let's go to catch and deport.”
Ramaswamy said that he was supportive of most of his opponents’ border positions, but that he’d go a step further: he’d end birthright citizenship for the kids of illegal immigrants.

“The Republicans on the stage are on the right side of this issue, militarize the southern border, stop funding sanctuary cities and end foreign aid to Mexico and Central America to end the incentives to come across,” Ramaswamy said.
