The fate of the Cuellar clan hangs in the balance Tuesday as South Texas residents head to the polls to determine if the embattled Democratic family deserves another shot in public office.

Rep. Henry Cuellar (D-TX) is seeking an 11th term as a federal lawmaker representing the Laredo area on the U.S.-Mexico border, but he could be the only one of his siblings to move forward to November after the others failed to secure at least half of primary voters in March. The congressman won his primary election by default earlier this spring because no one challenged him.
