Who Has More Delegates?

Barack Obama emerged with a majority of the state's at-large presidential nominating delegates and possibly a majority of all Texas delegates.

But Hillary Rodham Clinton's supporters vowed Sunday to continue the fight for Texas delegates all the way to this summer's state party convention, promising to cut his lead in delegates.

The actual number of delegates awarded to Obama and Clinton will not be official until the state party convention meets June 5-7 in Austin. The results of Saturday's regional conventions were still being tallied Sunday, but Obama was winning about 58 percent of the delegates to the state convention.

Candidates Counting On Texas Turnout

Texans probably will vote in record numbers today in the state's first presidential primary election that matters since 1988.

Texas' March primary usually comes after the Democratic and Republican nominees have been sewn up. This year, Democrat Barack Obama is counting on a Texas victory to widen his lead over Hillary Rodham Clinton and perhaps force her out of the race. Clinton is betting that winning the second-largest U.S. state will spur a comeback.

Optimism Increases For Obama In Texas

Democrat Barack Obama's first foray into South Texas on Friday showed signs that rival Hillary Rodham Clinton may win the region's popular vote but that he may break even with her in securing delegates for the presidential nomination.

While Obama's noontime crowd of about 3,000 at the University of Texas-Pan American was mostly made up of students who showed little enthusiasm, Obama drew about 6,000 supporters to the American Bank Center in Corpus Christi.

Another troubling sign for Clinton's South Texas hopes is that one of her main South Texas supporters, state Rep. Aaron Peña of Edinburg, appeared backstage at Obama's Pan American event and told a local news organization that Clinton would win the popular vote but Obama was strong in the fight for delegates.
