Bonilla had grown up in this area, which had been part of the 23rd from 1967-93. The court ordered an all-party primary on Election Day, with a December runoff if no candidate wins 50 percent of the vote. The new map included Rodriguez' home and much of his former base, and he announced that he would run against Bonilla in November. Federal Elections Commission records show Bonilla paid the Los Angeles-based law firm of Latham & Watkins $100,000 in 2006, from his campaign funds, to argue that the district boundaries were constitutional. In February, the firm filed an "amicus" brief before the Supreme Court in support of the redistricting plan.
