Politico.com launched Jan. 23, 2007, the day of that year’s State of the Union address. Early this morning, the site put up this video with well-wishes from tvnewsers including Bob Schieffer, Katie Couric, Dan Rather, Joe Scarborough, Mika Brzezinski, Willie Geist, Diane Sawyer, Candy Crowley, Norah O’Donnell, Luke Russert, Greta Van Susteren, Tom Brokaw, Chris Matthews, Jonathan Karl, Andrea Mitchell, Erin Burnett, Alex Wagner, Al Sharpton, and Dylan Ratigan.
