The data on Asian American public opinion reveal that Asian Americans are shifting in party identification towards the Democratic Party, and exclusionary rhetoric is a likely cause. There has been a 12-point increase in the proportion of Asian Americans who identify as Democrats from 2012 to 2016.
Asian American voters nearly doubled from more than 2 million voters in 2000 to 2000 to 3.9 million voters in 2012. Since in the last three presidential cycles, the number of Asian American voters has grown by an average of 620,000 votes, the 2016 turnout might be 4.4 million voters. Asian Americans will reach 5% of voters nationally by 2025. In battleground states in 2012, they were 6.5% of the voters in Nevada, 3.9% in Virginia, and 1.8% in Florida.
Trump’s unfavorability rate is 48% for 65 yo and older, 63% for 35-64, and 86% for 18-34 yo. 31% have a very or somewhat favorable view of the Republican Party, vs. 65% for the Democratic Party and 68% for Barak Obama.
This information is from a May, 2016 report, Inclusion, Not Exclusion. Apiavote stands for Asian and Pacific Islander American Vote.
2012 exit polls showed at least 70% of Asian-American voters chose Obama. Two decades ago, Asian-Americans reported voting Republican by a nearly 2-to-1 margin. See my post election posting here.
