Chris Matthews is best known for his opinionated and combative style on his MSNBC program, "Hardball with Chris Matthews." What's lesser known is that he's a former print journalist, was a long-time aide to Tip O'Neill, and that he grew up in an Irish Catholic family...of Republicans. All this played no small part in sewing the seeds of his admiration for a man he'd later write two books about, John F. Kennedy.
