Republican debaters mention the environment

In case any doubts remain, here is the only explicit mention of the environment (that I heard) in tonight's debate among Republican candidates for president:

"What we need is the mother of all repeal bills," Bachmann said, promising to get rid of Obama's national health-care law and new regulations on the financial industry and to rename the Environmental Protection Agency the "Job Killing Agency of America." (http://goo.gl/o88td)

Rick Santorum inadvertently took an implicitly pro-environment position, in mentioning his opposition to ethanol subsidies. I guess ethanol must not work in lubricants.
