The issue of supplying aid to Ukraine as the country remains invaded by Russia has been a major source of contention among the Republican party, even holding up budget negotiations as Congress barrels toward a government shutdown.

A few answers from the GOP candidates at the debate displayed the variety of opinion among the primary field. Christie, who shares the belief of establishment Republicans, spoke about his unrelenting support for Ukraine aid.

“That was the darkest moment in world history when the Soviet Union fell. Listen, everybody, [Putin] wants to put the old band back together, and only America can stop it,” said Christie, who noted that American leadership on the conflict could display strength in other areas of foreign policy.

“Ukraine – that's a green light to China,” Christie said. “They're all connected, Stuart. They're all connected. The Chinese are paying for the Russian war in Ukraine, the Iranians who supply more sophisticated weapons, and so are the North Koreans now as well, with the encouragement of the Chinese.

Christie bashed some of his primary challengers for their opposing views: “the naivete on the stage from some of these folks is extraordinary.”

DeSantis, like the right flank of the party, said he would not embrace continually funding the “territorial dispute.”

“It's in our interest to end this war and that's what I will do as president. We are not going to have a blank check. We will not have US troops and we're going to make the Europeans do what they need to do… Meanwhile, our own country is being invaded.”

Ramaswamy said the answer to the economy was to put people back to work, but the labor market is unusually strong, with low unemployment and cooling but steady job growth.

According to The New York Times, DeSantis has spoken the fourth-most of the seven candidates, behind Ramaswamy, Scott, and Christie. That's not the dominant performance that some of his supporters had hoped for, and it doesn't signal to viewers that he's the clear alternative to the absent Trump

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.
