After this morning's hour and twenty minutes of legal arguments and judicial questioning, the US Supreme Court will probably take until June to rule on the issue of same-sex marriage. Gay marriage advocates have targeted California's Proposition 8, which banned such unions five years ago. The justices have a plateful of options to consider. Will they uphold Prop 8? Will they rule that same-sex marriage is a constitutional right? As public opinion has shifted, will a court majority leave the issue up to different voters in different states? We hear excerpts from both sides, learn what the justices wanted to know, get analysis and perhaps even a brave prediction or two.
