<p>The Texas primaries are set for Tuesday, 9 March 2004. The U.S. Congressional districts in Texas have been significantly altered due to the re-districting battle last year. One heavily altered district is TX-10 which stretches from the western suburbs of Houston to Austin. Since the current office holder (Lloyd Doggett-D) is running in district TX-25, this is one district that many expect to switch from Democrat to Republican.</p>
