Asians are just going to trust the economics department at a university over the hobbyist/conspiracy theorist type thinking of conservatives.
Which is interesting, because in my experience, economics departments tend to be more conservative than other disciplines, anyway! Milton Friedman or whomever may have been respectable (if quite conservative), but the Republicans steady embrace of voodoo economics as a method of "starving the beast" in order to force austerity on the population is bad enough; the Austrian/Libertarian types that have gained currency on the Internet and among politicians like Rand Paul is even more out of the mainstream!
I think the Asian immigrants who came to the US in the mid-to-latter half of the 20th century were obviously more conservative than their children and grandchildren are. Those who
did vote tended to be wealthier and either in business/entrepreneurial or scientific/engineering occupations , which in that time, typically meant Republicans. Remember, American conservatism was quite a bit more mainstream and popular (Reagan, anyone?
) back then. Moreover, Reagan may have paid lip service to the Religious Right, but most of his philosophy focused on economics, reducing the size of government, and defeating the USSR. So I don't think it's a stretch to imagine that the more mainstream conservatism of the time would be popular among wealthy Asian-American voters, in addition to groups from Communist countries like the Vietnamese.
As far as the more assimilated generations of Asian-Americans go; Beet answered that better than I could.
