After the 2016 election, I was surprised to read that Asian-Americans voted about 70% for the Dims. Would have guessed they would have been closer to 50/50, or a small percentage in favor of Republicans. - Maybe they will vote more for Republicans in the future.
That is more the younger, suburban Asian-Americans. They go to elite universities and vote the way the graduates of those universities vote.
In the Reagan era Asian-Americans tended to vote Republican. Many of them had been refugees from Communist countries - China and Vietnam. But the younger generation doesn't have the same memories.
Japanese-Americans are the WASPs or Jews of Hawaii - the liberal establishment and mainstay of the Democratic Party. Indian-Americans tend - so far as I've seen - to vote for the party in power.
There is a paradox in assimilation. Traditionally, the more assimilated individuals and groups are, the more they vote Republican. But today, groups and individuals are assimilated to the category of Asian-American, African-American, Latino, Middle Eastern-American (and I suppose European-American) and they vote Democrat out of group identity and loyalty.
