The corruption trial of Antoin "Tony" Rezko, due to start in federal court in Chicago tomorrow, comes at a bad time for Barack Obama. The senator from Illinois is surging ahead of his rival Hillary Clinton in the Democratic race by presenting himself as Mr. Clean, untainted by the corrupt ways of Washington politics. But Obama's claim to be untainted by politics as usual, is seriously called into doubt by his alliance with the property developer and fast food franchiser Rezko, a close personal friend and one of his most generous donors.
