 Uresti, a San Antonio attorney, prevailed with 56.5 percent of the vote to Madla's 43.5 percent.Carla Vela, the then Bexar County Democratic Party chairman, said that issues were less important in the Madla-Uresti race than an ongoing intraparty power struggle involving the political families who control the Southside section of San Antonio.Shortly after his primary defeat, Madla announced that he would resign his Senate seat early, effective May 31, 2006.
