Is he a trumpist option or just a MUHHH FISCALLY CONSERVATIVE BUTT MODERATE option?
He's a pretty generic Chamber-friendly Republican. He was a state/federal attorney before he ran for Congress, but he's filthy rich because he married into the Mays family, which owns Clear Channel Communications (one of the largest radio station networks in the country). He seems mainly interested in foreign policy/defense issues and I think he just generally votes with leadership on everything else because he doesn't care all that much.
It would be interesting because Texas has never had a foreign policy-focused senator that I can recall. They tend to either be domestic policy ideological crusaders (Gramm and Cruz from the Right; Yarborough from the Left), pork farmers (Kay Bailey Hutchison, Lyndon Johnson) or party apparatchiks (Bentsen, Cornyn).
