Suburbanite Asians in California and New Jersey vote Democrat. Check the election returns for the San Gabriel Valley or the portions of Middelsex and Bergen counties in NJ that are heavily Asian, and you will see a heavy vote for Obama.
In general an area has to be below 1,000 people per square mile to reliably vote Republican. Even when Asians move to the suburbs they prefer high density housing, big houses on small plots of land, with the next door houses about 5 feet away. They are ok with big gov style HOA rules and regulations, a requirement for orderly high density living.
