U.S. Representative Lloyd Doggett of Texas has announced that he will not seek reelection if the new congressional redistricting map is upheld by the courts. This decision paves the way for his fellow Democrat Greg Casar, as the two consider competing for the same seat following the redistricting process. Doggett, a longtime member of Congress, expressed his commitment to passing the torch to a new generation of leaders and indicated that he would step back if the legal challenges to the proposed maps do not succeed. The situation has raised concerns among Texas Democrats about the potential for an incumbent-vs.-incumbent battle as they navigate the shifting political landscape.
