The first vote was cast before gay marriage was legal anywhere in the nation. Eight years later, both Massachusetts and California allowed same-sex couples to wed. Whether gays should marry was now a cultural battleground. Polls showed young voters overwhelmingly for gay marriage. Older voters, churchgoers and African Americans tended to be strongly against. The two sides fighting over Proposition 8 raised more than $83 million in the nation's costliest ballot measure this year.
