David Boies and Ted Olson, both 69, are lions of America's legal establishment Boies, a darling of the left; Olson, the right. Time and again they've clashed, most famously in Bush v. Gore, in 2000. Olson won that battle, and given how high the stakes were, the two lawyers might be forgiven any lasting bitterness. Instead, they've become great friends.
So perhaps it is not shocking that this odd couple teamed up to challenge the constitutionality of California's prohibition of gay marriage. They've put on an extraordinary case in the federal court system and could prevail in their long-shot mission.
In today's debates, polarization and personal attacks have replaced civility and excellence. It says a lot about Boies and Olson that they can disagree profoundly about legal issues without losing respect for each other. They remind us that the ideas binding us together in our constitutional democracy are far more important than those separating us.
