admitted to believing in climate change and that humans are at least partially responsible?
Unless you mean Schiavo is part of his conservative creds.
I "may" end up voting for him, depending on a lot of factors, but if I do it will be "in spite" of what he did to Terry Schiavo, and NOT because of it.
Will his R opponents use it against him? Sure. Will it matter much? No.
This is just not an issue the average voter is going to care about much. Plus, he is just wish washy enough on it for it not to bite him in the ass.
GW is a multi-layered issue. For example, one can believe in "climate change", as I do, meaning the climate is never static, and can also believe humans are "partially responsible" (which is so vague to mean practically nothing) and yet do not believe it is an existential threat to the planet/our survival.
Those beliefs are not mutually exclusive and that appears to be Bush's view.
Bush's problem is going to be the border and Common Core, not GW
