All the senators debating the war supplemental are calling Barack Obama "Mister President."
No, it's not an unprecedented bipartisan endorsement of his 2008 candidacy from everyone in the chamber. The Illinois Democrat is sitting in the president's chair, acting as Senate president pro tempore.
But what's more fun for Obama, elected to the Senate in 2004, is that none of his Democratic rivals for the nation's top office will get the pleasure of being called "Mister President" (Or Madam President, for that matter) on the Senate floor.
Why? He's the most junior of all his colleagues running for president, and the freshmen and sophomore senators are given the mundane task of running floor procedure.
