Also there is a major reason that many asian MALES vote democrat that no one, to my knowledge has brought up yet. Namely the reason is that the democrat party is pretty much explicitly anti-white male. The majority of asian american males (whether they openly admit to it or not), dislike seeing their women poached by white guys. Thus, asian guys see a vote for democrats as a way to get back at white males.
Furthermore, the democrat party is also known as the party of black people (black men). And who else is better at "getting back at whitey" than the black man? So in a nutshell, asian american males also vote democrat in order to empower black males in a proxy war against the white males who are stealing the asian girls.
Yup, that's why Asians voted for Obama.
