It is for U.S. House District 28.
He is running against Victor Morales and Ciro D. Rodriguez with Rodrigeuez being the one pushed by the DailyKos.
I was wondering why the thugs who were heckling Cuellar were "white", rather than hispanic..I found the answer.
They were out of state Union thugs. Real class act, Ciro.
From the Express-News:
In San Antonio, United Steelworkers of America volunteers heckled Cuellar, 50, when he showed up at an East Side polling place to troll for last-minute votes.
San Antonio needs a Democrat, not a Laredo Republican, shouted Peter Kaval of Pittsburgh, a steelworker who spent three weeks in San Antonio to help Rodriguez reclaim the seat he lost to Cuellar by 58 votes in 2004.
