Mike McCaul and Houston-area mortgage banker Ben Streusand emerged from a field of eight Republicans in the March primary to qualify for a runoff. Streusand had 28 percent and McCaul 24 percent in their first-ever run for office.
In what became one of the most expensive congressional races in the nation, the pair combined to spend some $5 million for the seat in the 10th District, which was reconfigured in 2003 by the GOP-controlled Texas Legislature to ensure a Republican winner. No Democrat ran in the primary.
In the April 2003 runoff, McCaul won easily with 63 percent of the vote.
