Over the next months, we'll see who's the chicken: President Barack Obama or congressional Republicans.
The death of Supreme Court Justice Antonin Scalia has prompted a heated battle over the president's duty to nominate a replacement. With the November elections looming, it's a game of political chicken with a twist and an interesting look at behavioral economics in the real world.
Obama has a number of options. If he nominates a liberal justice akin to his two previous nominees, Sonia Sotomayor and Elena Kagan (who were both confirmed by the Senate), the Republican-controlled Senate has promised to block such a nominee.
But senators might have a harder time explaining it to their constituents in November if they block a moderate nominee. They could be labeled as obstructionists shirking their constitutional duty simply to score political points.
