"Texas needs to be less dependent on the federal government, not more. These politicians want to mismanage our electric grid just like they mismanage our border," the statement said.
I don't think it's objectively possible to be more mismanaged than the current Texan electrical grid.
I don't even know if it's corporate profits, that's actually a drawback to the corporate grid(see Enron's intentional mismanagement of California's energy grid)
It's just pure power for the ruling elite of Texas.
