Eleanor Darragh, Sen. Ted Cruz’s mother, speaks during an campaign event with her son, his wife, Heidi (center left) and Carly Fiorina Wednesday in Madison, Wisconsin. In speech after speech, the Texas senator and Republican presidential hopeful has recounted for audiences the story of how his father fought for freedom in Cuba before escaping to the United States to embrace the American dream. Rafael Cruz’s biography has been the emotional and inspirational bedrock of son’s bid for the White House, and as such, he has been one of the senator’s busiest and most recognizable campaign surrogates.
