A new poll shows that the vast majority of California's Asian-Americans oppose Proposition 8, the state's ballot measure that would overturn the state supreme court's May ruling and outlaw same-sex marriage, reports the San Jose Mercury News. The poll found that 57% of likely Asian-American voters planned to vote against the amendment, while 32% said they would approve the measure. Asian-Americans in California also favored Sen. Barack Obama over Sen. John McCain for president 42%-24%, with 33% undecided -- almost identical to the poll's national Asian-American numbers of 41%-24% favoring Obama with 34% undecided. The National Asian American Survey of nearly 1,900 Asian Americans statewide was administered in eight different languages, cost $300,000, and is the largest poll ever conducted of Asian-Americans both nationwide and in California.
