McAllen attorney Jaime Gonzalez Junior confirmed today that he's endorsing Clinton. He says he based his decision, in large part, on Clinton having won the Texas primary and the Hispanic voters who came out to vote for her.

Gonzalez is one of 32 Texas superdelegates targeted by the campaigns of both Clinton and rival Barack Obama over the past weeks and months.

Clinton appears to have a slight edge among Texas superdelegates. Twelve have told The Associated Press they've pledged to her, while 10 say they're supporting Obama.

Clinton leads among superdelegates nationally, though Obama has been closing in.
