The major television networks have declared Hillary Rodham Clinton the winner of the hotly-contested Texas Democratic primary but Barack Obama appeared headed to a win in the delegate rich caucus.

Even with a loss in the popular vote, Obama could leave Texas with the most delegates and hold on to his lead in overall delegate count.

Major networks made the call in Texas at 12:50 a.m. With 75 percent of the vote counted, Clinton had a 51-48 percent margin over Obama. The win gives Clinton wins in Texas, Ohio and Rhode Island while Obama won Vermont.
