During the Franken – Coleman senatorial campaign in Minnesota, Republican Norm Coleman issues a number of very negative campaign ads filled with misrepresentations and lies about Al Franken. Meanwhile, Democrat Al Franken issued ads critical of Norm Coleman. There was a difference: Coleman’s ads were lies, Franken’s ads were accurate. Nonetheless, Coleman, known not only for is womanizing, graft-mongering, and other things I won’t mention, but also known for a litigious streak, sued Franken over two claims made in campaign ads. One of these claims was determined by a judge to be a matter of opinion, and thus not actionable. The second, a claim about corruption, was determined to be substantially true.
That is not quite exactly like being convicted, but damn close!
