Just googled it and you’re correct. Nationally, Vietnamese-Americans were the most Republican friendly asian demographic. Only 44% of them voted for 0. However, Filipino-Americans were the second most GOP-friendly group, and together they were the only two asian ethnicities that voted Republican by plurality. (again, it appears to come down by generation gap... Filipinos under 30 heavily supported Obama, Filipinos over 65 heavily supported Romney). The least GOP-friendly asian demographic was Bangladeshi-Americans. 96% of them voted for 0.
Bangladesh is a Mohammadan hellhole, so no surprise which way they’d vote here, unfortunately.
That little weasel Manny Pacquiao, a folk hero to Filipinos, endorsed Harry Reid and Jerry Brown, that certainly hurt GOP performance among Filipino-Americans in those races.
