Actually, Asian Americans are more likely to become Republicans first, under any realignment. They voted 48-50% (50-50?) for the GOP in 2014 and their economic situation is strong enough that if social issues were taken off the table, they would be part of any GOP coalition in the future. I think Asians are just ticked off at the GOP's social issues (since a ton of Asians are highly educated and there's an education divide).
It's not remembered but Bush won 44% among Asians too. Coincidentally, the 44% in both Latinos and Asians matched his CA performance in 2004.
I don't think it's so much social issues (didn't Asians narrowly vote for Proposition 8?), but it's more, as you said, the GOP's pandering to the rubes and their anti-intellectualism that turns so many Asians off. Asians value higher education and they don't see Ivy League universities and those with doctoral degrees as "liberal elites;" rather, they see these places as institutions of honor and prestige. Asians don't want to be associated with the stupid party that is represented by heehaws like Phil Robertson and Kim Davis, and the Trumptards' hijacking of the Republican Party and the war on facts probably just turns off more Asians even more.
Do you people even try to hide your classism anymore?
Being stupid is not necessary "classism" you can be poor but value education or be rich but stupid (heck our president fits in that second part)
