In San Francisco, same-sex couples made it a point to tie the knot before Election Day, because if Proposition 8 passes, same-sex couples will no longer be able to marry in California. That is why Monday night was bittersweet for Mike Horwatch and Curt Hancock, who could very well be among the last gay couples to marry in the state.
"For anybody to take that away from someone else, it's sad, it's really, really sad, and I don't understand the concept or the thought behind it," said Horwatch, a newlywed.
Proposition 8 is one of the most closely-watched ballot measures nationwide and it's said to be the country's most expensive social initiatives ever.
So far, the "Yes On 8" Campaign has raised nearly $36 million, while the "No On 8" Campaign has raised nearly $38 million for a combined total of more than $73 million.
Most of the money has gone to television ads that have blanketed the airwaves in recent weeks. Many supporters of Proposition 8 say, despite the fact the polls show a dead heat, they're optimistic they will prevail. They say their demonstration in Pleasanton Monday night was well-received.
"I'm from Southern California, I do live in the Bay Area now and it is way more liberal so I am just warmed by the response, by the positive response. It's amazing," said Bridget Melson, a "Yes on 8" supporter.
"Unfortunately, four activist judges thought they could legislate from the bench and the people aren't going to stand for that," said Stacy Kennedy, a "Yes on 8" supporter.
Still, opponents of Prop 8 say the people aren't going to stand for inequality either. That's what they hope anyway.
"I am, I am worried. Hopeful, but worried," said Deni Paul, a Prop 8 opponent.
No matter which way the election goes, one thing is certain, Mike and Curt have said their vows, and they say no one can take that away from them.
"I can't imagine spending the rest of my life with anyone else. And he's the one," said Horwatch.
