AUSTIN -- Democratic presidential candidate Barack Obama has tapped San Antonio attorney Juan Sepulveda to head his Texas presidential campaign.

Sepulveda is a member of Obama's National Latino Leadership Council and served as a senior adviser for Bill Bradley's 2000 presidential campaign. He also has worked to increase the political participation of Hispanics.

Texas Democrats hope to capitalize on Obama's presence in downballot races.

Sepulveda is president and founder of The Common Enterprise, which helps nonprofit groups, philanthropic organizations and businesses build stronger communities.
