Off to the races: GOP stance on marriage 'no longer a winning one'

Dan Balz notes that on gay marriage, “GOP leaders know their position is no longer a winning one.” More: “The Supreme Court justices can see the contours of this debate — rapidly moving public opinion along with generational and geographic differences — and may choose not to deal directly with the California proposition. Absent a Supreme Court decision, the battle to legalize these unions will be waged state by state, with a patchwork that probably will divide red states from blue states. … But many politicians aren’t waiting for the court to act.”

Politico: “As the Supreme Court takes up same-sex marriage on Tuesday, a growing number of young Republicans are waving the white flag in the culture war over gay weddings — with many opting to focus on economic issues instead.”
