Lloyd Doggett, D-Austin, to switch to a different district for his re-election bid, and opening the door for longtime local car dealer Roger Williams to run for - and win - that seat. Now Williams says he wants to serve a second term representing the district that stretches from the edges of Tarrant County to the Hill Country.
