Interesting.
Republicans actually won the Asian vote in 1992 and 1996. Of course, Asians made up a much smaller % of the electorate then.
Vietnamese voting Republican by a 56% - 44% margin is comforting. My guess is that they are like Cuban-Americans, who are attracted to the anti-communist ideology in the GOP.
Indians should vote GOP. Right now, 65% of Indians in India live in rural areas. They are conservatives. Gandhi, the legend among Indians, opposed cities and modern ideals. Shouldn't they be anti-technology, anti-science, and anti-intellectualism, like Southern whites are?
If Republicans can reach out to them successfully and articulate their beliefs, Indians can and should get in their corner.
Most Indians are White-collar recent immigrants. Very few Indian immigrants are the folks in rural areas. Also, many of them are Muslims.
