I don’t think I’ve ever seen a breakdown of Asian voters into various nationalities, as far as how they vote.
Polling that the company I work for does (polls which are only semi-political and not for any candidate or party) indicates that Indian-Americans are one of the most liberal groups out there. Maybe that’s just a California bias in the polling, but I don’t think so.
