 "Joe Biden")
Joe Biden has won the Democratic primary in Texas, US networks projected, handing him a key victory over Bernie Sanders, his main rival for the party's White House nomination.
The result in Texas -- where the leftist Sanders had been polling ahead -- capped a remarkable night for Biden, who was projected to win a clear majority of the 14 states voting on Super Tuesday.
With 228 delegates in play, Texas was the night's second-biggest prize behind California, where exit polls projected a win for Sanders.
