Playing the China Card. Romney mentioned China 20 times in the second debate. In the debate, Romney blamed China for the downturn in employment and manufacturing in the United States, and reiterated that China would be listed...

Romney also attacked China for infringing on intellectual property rights. Romney intends to gain an advantageous position in the debate and gain votes by playing the "China card". But Obama's fierce counterattack made his "China card" ineffective.

On the issue of RMB exchange rate, Obama said that since he took office as president, the RMB has appreciated by 11% against the US dollar. He attributed the appreciation of the RMB to the United States, which was inconsistent with the facts, but he also clearly pointed out that Romney turned a blind eye to the sharp appreciation of the RMB.

During the debate, Obama also pointed to specific examples of Romney's investment in China in an attempt to show that Romney was duplicitous. Although he verbally cursed China, he was actively doing business with China behind the scenes. Obama bluntly told Romney that he was "the least qualified person to take a tough stance on China."

Romney and Obama mentioned China as many as 20 times in this debate, most of which were related to economic and trade issues. As the U.S. economy is still weak, China has become a target for the two presidential candidates to shirk responsibility and deflect conflicts.

Obama also showed a tough side towards China during the debate. He has also recently demonstrated his "tough stance against China" with practical actions, including announcing that he would accuse China of subsidizing the export of automobiles and parts to the WTO.

After the second presidential debate, a national poll conducted by CNN/ORC International showed that 45% of voters who watched the debate believed that Obama won, and 39% believed that Romney performed better.

In terms of the support rate of the live audience, Obama gained a 7 percentage point advantage. But polls also show Romney performs better on economic issues. The two candidates were tied on whether the debate affected voters' voting decisions. Half of those surveyed said the debates would not make them more likely to vote for a particular candidate.
