A few weeks ago, I communicated with a Chinese woman in Thailand who was shocked that most Chinese-Americans support Trump. I was shocked that she thought most Chinese-Americans support him, since I had presumed that a majority of Chinese-American voters would choose Biden.
Curious, I found this (pre-election) survey. Their results were that 56% of likely Chinese-American voters planned to vote for Biden, 20% for Trump, and 23% were undecided. I was right to guess that a majority of Chinese-American voters planned to vote for Biden, but that majority was smaller than I expected.
In my research, I found that Chinese-Americans who immigrated as adults were more likely to support Trump than American-born Chinese (ABCs) or Chinese-Americans who immigrated as children. This did not surprise me.
