I can’t find anything on him. Are you sure you have the name right? Perhaps you mean Wayne Christian?
Katrina Pierson is a big Tea Party leader down there who worked with Cruz. She should consider a run.
When I got back from a few days of vacation I had over 400 emails. One of them was from a website called STOP AGENDA 21 IN TEXAS. It included a link to their website: www.stop21texas.com which had an article on Wayne Stovall with a statement saying that he was either thinking about or was throwing his hat in the ring to run against Cornyn.
Apparently he does have his own website and Facebook page. I looked at his website briefly and don’t recall that he has ever held office before. Haven’t seen anything about him on any other sites and just haven’t had time to check further. If you get a moment you might want to take a gander. It’s really early yet but Cornyn has been building his warchest for several years and will be difficult to oust - but nothing is impossible.
Wayne Christian is very conservative but was repudiated by his own district “Republican” voters in the 2012 primary. He has no statewide recognition.
