"Breaking: key vote Kennedy VERY uncomfortable striking down #prop8."

"Suggests dismissing case. Would leave in place 9th Cir pro-#ssm ruling."

There are not 5 votes to strike down #prop8 and recognize equal right to #ssm at this time

SCOTUSblog tweets from the oral argument.

Note the significance of "Would leave in place 9th Cir pro-#ssm ruling." Prop 8 will still be stricken down, because that's what the 9th Circuit decided. I want to see the transcript (and hear the oral argument) before reacting too much to these characterizations.

So Kennedy performed the Theater of the Very Uncomfortable. That could set the stage for exercising the very painful duty of pronouncing a law a nullity. It's supposed to hurt! It's not what we want, but what we must do.

(Calling judicial review a "painful duty" has a long pedigree.)

MORE: Here, from SCOTUSblog's Tom Goldstein:

The Justices seem divided on the constitutionality of Proposition 8 on ideological lines, four to four – i.e., all the members other than Justice Kennedy. For the more liberal members of the Court, there was no clarity on how broadly they would rule.

But Justice Kennedy seemed very unlikely to provide either side with the fifth vote needed to prevail. He was deeply concerned with the wisdom of acting now when in his view the social science of the effects of same-sex marriage is uncertain because it is so new. He also noted the doubts about the petitioners’ standing. So his suggestion was that the case should be dismissed.

If those features of the oral argument hold up – and I think they will – then the Court’s ruling will take one of two forms. First, a majority (the Chief Justice plus the liberal members of the Court) could decide that the petitioners lack standing. That would vacate the Ninth Circuit’s decision but leave in place the district court decision invalidating Proposition 8....

Second, the Court may dismiss the case because of an inability to reach a majority. Justice Kennedy takes that view, and Justice Sotomayor indicated that she might join him. Others on the left may agree. That ruling would leave in place the Ninth Circuit’s decision.

But of course Kennedy would hang back in contrast to the 4 liberal Justices. His difference from them doesn't mean he won't join them in the end.

I'll say more when I've heard the argument myself.
