Sorry, my brain broke traction there for a moment. My apologies to Garrison. Roger Williams is indeed Riddle's opponent, supported by the same crowd as Dewhurst. Garrison was one of the primary candidates who didn't make the cut but has endorsed Riddle in the runoff.
I've met Wes. He founded Central TX Tea Party. I don't read him as a hardline Paulista but the southern end of TX25 seems heavily Paul country so I don't think it hurts to have his endorsement.
I hope Riddle wins today!!!
