Arabs are not classified as Asians. Also, Obama getting 80% of the Muslim vote? Sure. 89% of the Arab vote? Hell no. For one, most Arab-Americans are Christians.
Also to add Filipino and Vietnamese-American's are one of the more conservative ethnic groups in the US. So no way Obama did very well amongst ether group or for that matter that McCain got less then 55% amongst the Vietnamese. Even the younger generations in both communties tend to be Republicans.
Filipino Americans have historically been very Democratic on the West Coast. They're the mainstay of the HI Democratic Party.
