Map shows keys to Romney's win in Florida

With votes still coming in, the map below helps illustrate Mitt Romney's strong night in Florida. He is ahead in counties throughout the state, dominating in the southern area around Miami, along the coasts and around vote-rich Tampa, Orlando and Ft Myers. Meanwhile, in the panhandle, Newt Gingrich's county leads come mainly from smaller counties - not nearly enough for him to make up the difference.
