SACRAMENTO, CA- Opponents and supporters of gay marriage studied the transcripts of Tuesday's Supreme Court hearing on gay marriage for clues to an eventual ruling.

"I think the fact that we've gotten this far, that there's this much exposure, that its made it into the highest court, I think is amazing. Who knows what will happen from here," said Regina King, a supporter of gay marriage who joined dozens of others at a rally on I Street in front of Sacramento's federal courthouse.

Same sex marriage opponent Randy Thomasson, with, agreed that the court could rule either way, and agrees with most observers that former Sacramento resident and Supreme Court Justice Anthony Kennedy could be the deciding vote.

"Anthony Kennedy is, for all reasonable people, the deciding vote. He seems not to want to be pigeon-holed, however, and some of those who've watched him say he gives some words for both sides," Thomasson said.

Thomasson believes the case challenging Proposition 8, that California voters passed in 2008, should not even be considered by the high court because it's an issue of state's rights.

"(The justices) should see state's rights in the 10th Amendment and see a constitutional, republican form of government inSection 4, Article 4 and say 'I give up, this should not have even been here, this is a state initiative, they're the law, not us,'" Thomasson argued.

For King, the issue should be addressed by theSupreme Court becauseof the implications for her rights as a U.S. citizen.

"There's over 1,100 federal rights that we're denied, you know, that heterosexual couples are not denied.Just the fact that my partner is pregnant, she's having a baby inJuly," King said."In California, we're a legal family. At the same time, you drive to Nevada and you are no longer recognized as such."

The high courtis expected to rule in the case by late June.
