The unfortunate thing is that Asians, while not as Democratic, are following in their footsteps, for the same reasons.
I disagree.
As recently as 1996, Asian American voters gave Bob Dole a plurality of 48%-44% over Bill Clinton.
What's happened is massive legal immigration from Asia.
Asian Indians have been the largest immigrant group from Asia for about 20 years, and they voted 90% or higher for Obama in 2004 and 2008.
I believe Chinese are the second largest Asian group in recent decades, and they vote around 75% for the Democrat Party.
The changing character of Asian immigrants also plays a role.
Asian Indians are often very well educated, but they remain overwhelmingly Leftist, like their home country.
Immigrants from the other Asian countries usually have limited education and limited skills, which makes them a prime voting target for the Democrat Party.
