In a free market price is a message. Shooting its messenger is a liberal move. If it's not a free market, eg. the government is taxing or charging Peter to subsidize Paul, everyone in group Peter should protest through all appropriate channels.
So furious Texans need to adjust targeting. I'm not saying there aren't problems in the GOP there, but this was caused by the new team of Feds even more than by the weather. Redirect volleys of emails, phone calls, etc. according. Stop shooting Cruz and start shooting via him as your representative. Heck, even Cornyn should be a useful conduit on this. Encourage your AG to investigate whether any legal recourse is available, criminally or civilly, for the damages caused. Maybe the size of the mandated price hike qualifies as some kind of malicious exception to the Feds' "I'm just doing my routine duty defense." There probably isn't, but he may be able to make enough noise to correct the narrative.
