A new poll says nearly half of Americans approve of legalized sports betting. The Fairleigh Dickinson University PublicMind poll finds 48 percent support changing federal law to make sports betting legal throughout the country; 39 percent are opposed. The poll comes as New Jersey opens another front in its eight-year war on a federal law restricting sports betting to those states that met a 1991 deadline to legalize it: Nevada, Oregon, Montana and Delaware. The biggest reason supporters are for it, so many people already do it illegally.
