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

Trump maintains a lead of 27 percentage points over Haley, his nearest competitor in South Carolina, according to polls conducted since the first debate. Haley’s average support has grown by 9 points since the first debate, while DeSantis and Scott have fallen.

According to a September survey from Beacon Research/Shaw & Co. Research/Fox Business, 69 percent of likely South Carolina Republican primary voters say they support their first-choice candidate strongly, while 28 percent say they support them only somewhat. Among those that list Trump as their first choice, 86 percent say they support him strongly, while the second-place candidate, Haley, has only 57 percent saying the same.

In a September survey by Monmouth University/The Washington Post, South Carolina primary voters are split on whether the Republican Party should nominate a candidate who agrees with them on major issues (51 percent) or one who can beat Biden (45 percent). Among voters who say they are very or somewhat conservative, selecting a candidate who can beat Joe Biden is more important by a margin of 7 and 11 percentage points, respectively. Voters who say they are moderate or liberal prefer a candidate who agrees with them on major issues by 31 percentage points.
