Good morning from The Virginian-Pilot. I'm Sam Scholl, and here are our top headlines for March 4th. Former Vice President Joe Biden won the Democratic presidential primaries in Virginia, North Carolina, Tennessee and Alabama as he swept the southeastern states voting on Super Tuesday. His win in Virginia reaffirmed the state's preference for moderate candidates over more progressive ones. Biden beat out Vermont Sen. Bernie Sanders, former New York City Mayor Michael Bloomberg and Massachusetts Sen.
