How? Hawaii has a state constitution backing their decision. What can the EPA do? Say they Regulate climate emissions and ban oil extraction tomorrow. What happens? Texas and the other red oil producing states just fall in line? They say "gosh, I guess they can tell us what to do even though my boys on the cout said they can't, oh well, we lose"

Of course not. Blue states tend to not need to be told what to do and are often the ones making the standards that are later imposed by the EPA nationally (see CARB standards still regulating MPG for example). So the EPA will be telling red states what to do, with no authority to do so and you seriously think they will just...do it? In what universe do you live, because I'd sure like to be there.
