Re: If the current Republican front-runner --
Cruz is also a hardcore anti-environmentalist. Climate change mitigation efforts, industrial pollution regulations, endangered species protection, the Clean Air Act - his position on all of them is that he'll get the laws repealed if he can, and if he can't then he'll block all funding for enforcing them, and specifically that he wishes to abolish the EPA entirely. He's gone on record on a several occasions stating that he believes there is no such thing as anthropogenic climate change, and that if there is then it'll be ultimately beneficial.
