No, very unlikely
Yeah, you have this poll which has Trump leading by only 2 BUT if you average the 4 most recent TX polls we have Trump is leading Sanders by a more confortable 6 points margin, let’s be clear the idea that Trump would win TX by double digits against Sanders because mUh sOcIaLiSm is absurd, TX is trending to the left and Trump is far from beloved in the state but in the end, considering Sanders vulnerability on energy issues and his love for foreign communist, anti-American dictators Trump would probably win TX by a healthy margin (something like 52/46 would be relatively reasonable)
Bernie is a bad fit for Texas. Just like Beto O’Rourke he wants to abolish ICE while Texas is on the frontline of the border crisis, which will give Trump an opportunity to label him as an extremist and that is part of the reasons why Cruz won in 2018 because O’Rourke was obviously too liberal for Texas.
