LOUISVILLE, Ky- U.S. Senate Majority Leader Mitch McConnell has literally written the book on how to have a long career in politics.  His 2016 memoir is actually titled, "The Long Game," and a win in 2020 could be the beginning of a fitting epilogue to a long, successful career.  Kentucky democrat Amy McGrath wants to write her own book and it includes turning a red Senate seat blue, while running against a politician who has been unbeatable for more than 30 years.
