Haley spars with Republican rivals at 3rd primary debate as Trump still looms

The two candidates who have perhaps the most acrimonious relationship on stage, Haley and Ramaswamy, have spent a notable amount of the debate sparring with each other.

After Ramaswamy mentioned that Haley's daughter has used TikTok, despite Republican criticism of the Chinese-owned app -- drawing boos from attendees -- Haley admonished him.

"Leave my daughter out of your voice," she said, adding with an eye roll: "You're just scum."

DeSantis said the U.S. Navy isn't large enough and he'd expand it significantly to meet China's threats. Right now, the U.S. Navy has 291 ships but DeSantis says his plan would be 385 ships by the end of two terms.

The Florida governor compared the threat of China today to the threat of the Soviet Union post-World War II, warning a Chinese superpower would want to "export authoritarianism" around the world.

"I think the future of freedom is going to be determined in the Indo-Pacific," he said. "We have a strategy not just with military but decoupling from the economy and fighting them here at home."

He then went after Haley for recruiting Chinese companies to invest in South Carolina when she served as governor, while he's worked to ban Chinese citizens from buying land in Florida.

Americans once had fairly mixed views of China, but they have become far more negative in the past five or so years, based on data from the Pew Research Center. In 2018, 47% of Americans had an unfavorable view of China while 38% had a favorable one. But that unfavorable percentage shot up to 60% in 2019 and it's only risen further since -- a whopping 82% said they had an unfavorable view in 2022. The national security and foreign policy attacks that Republican candidates have made on China in this debate likely resonated, although Americans tend not to list overseas concerns as a top worry.

Scott, Haley and Christie sounded support for Ukraine against Russia while Ramaswamy and DeSantis were more skeptical of how much Washington should back Kyiv.

"We have been very effective using our resources and our weaponry and the very high price of Ukrainian blood to achieving that objective," Scott said of degrading Russia's military.

Still, Scott argued, "The American people are frustrated that they do not have a president who reminds us and tells us where's the accountability -- how are those dollars being spent? We need those answers for us to continue to see the support for Ukraine."

Haley said she does not support handing Ukraine cash but that the U.S. should "give them the equipment and the ammunition to win."

Christie, meanwhile, argued support for Ukraine "is the price we pay for being leaders of the free world."

Ramaswamy, who has hammered Ukraine throughout his campaign, called Ukraine corrupt.

"To frame this as some kind of battle between good and evil, don't buy it," he said.

DeSantis, meanwhile, sought to pivot to immigration but said, "We are not going to send your sons and daughters to Ukraine."
