Good luck. I’ve poured resources into election his primary challengers for the past 3 elections but Texas voters are to ignorant, too corrupt, or both. Cornyn always wins primaries by wide margins. Not even this will hurt him. We have a seriously expansive swamp here in Texas. All the way back to LBJ.
Indeed, Cornyn may be the most untouchable Senator of all time. Nobody will come close on a primary.
