Democratic presidential candidates Barack Obama and Hillary Clinton square off Thursday night in another debate.
It's being held in a gym at the University of Texas at Austin.
Both candidates have been crisscrossing the state in advance of the March 4th, delegate-rich Texas primary.
Obama leads in the overall hunt for delegates to next summer's nominating convention. He's won the last 10 state contests in a row, including votes Tuesday in Wisconsin and Hawaii.
The Associated Press delegate count shows Obama in front with 1,336 delegates to Clinton's 1,251. It takes 2,025 delegates to win the Democratic nomination.
