From a public relations standpoint, getting forced out of the Illinois governor's mansion a year and a half ago was a smart career move for Rod Blagojevich. He's been all over the TV since, doing stints on such shows as "Celebrity Apprentice" and "The Late Show with David Letterman." But publicity may not be enough to keep him or several of his former allies out of prison. His long-awaited trial on fraud and conspiracy charges related to his attempt to sell Barack Obama's pending Senate vacancy to the highest bidder began on June 8, the result of a five-year Justice Department probe into corruption in Chicago politics. Prosecutors wrapped up their case just before 5 P.M. Tuesday. Evidence introduced thus far confirms widespread suspicions that former Gov. Blagojevich and his benefactors were part of a larger Chicago-Obama White House conduit.
