In yesterday’s New York Times, Stephen Colbert took over Maureen Dowd’s regular opinion column and made a funny case for why he could be the next US president. Read it here. Also listen to his interview last week on NPR’s Fresh Air (iTunes – Feed – Web Site). These appearances all figure into a media blitz designed to boost sales of Colbert’s newly-released book I Am America (And So Can You!), which is already #4 on Amazon’s bestseller list. Not bad.
