Unconfirmed sources: President Bush endorses Stephen Colbert

President Bush finally repaid his debt for Stephen Colbert's unqualified support at the White House Correspondents Dinner. True to form, he gets it wrong and accidentally endorses Colbert for vice-president on a Stewart-Colbert '08 ticket. Nonetheless, when a President with these kinds of approval ratings endorses you, there is no place to go but up, baby.
