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.
Everyone in Hawaii is the mainstay of the HI Democratic Party. Hawaii is probably the most heavily Democratic state in the United States, except for the possible exception of Massachusetts, and I'm not so sure about that.
Kerry only won the state by 9 points in 2004. Obama's margin of victory in 2008 was mainly a native son effect.
It certainly leans to the left but you can't really peg it as super Democratic. It kind of does its own thing out there in the ocean.
