With most predicting he will go down in defeat, Democratic Sen. Russ Feingold earned compliments from his former GOP ally, Sen. John McCain, on Monday. The Arizona senator and 2008 GOP presidential nominee has campaigned hard for Republican Senate candidates this cycle while sharply criticizing their Democratic rivals, such as Sens. Barbara Boxer (Calif.) and Patty Murray (Wash.) But McCain saved kind words for Feingold (Wis.), with whom he worked on landmark campaign finance reform legislation eight years ago.
