The arguments at the Supreme Court over California’s Proposition 8 are over. By all accounts, the questions were tough. And tweets from the authoritative Scotusblog raise serious doubts that the high court will issue a sweeping ruling granting same-sex couples a constitutional right to marry.

We’ll get to see the transcript and hear the audio of the arguments today, but, as I have been cautioning friends for a week now, we can’t tell how the justices will rule based on their oral arguments. Remember the rending of garments after the hearing on the Affordable Care Act (ACA)? Folks thought for sure that Obamacare would be declared unconstitutional based on the questions asked and what many thought was a disastrous performance by Solicitor General Donald Verrilli.

The law was upheld. President Obama’s major legislative accomplishment was saved. And the tea-leaf readers at the Supreme Court were caught flat-footed. Now that the arguments have concluded in the Proposition 8 case, the waiting for a decision begins. We’ll know by June what the court thinks.

I have a good feeling. Maybe it’s because I’m an optimist. Or maybe it’s because I believe in the promise of our Constitution.
