Next Stop, the Twilight Zone
February 7, 2009 9:22 pm | by by Jason Lomberg, Technical Editor | Blogs | CommentsObama’s position on tailpipe emissions presents a strange paradox: traditional supporters of states’ rights are clamoring for one national standard, while federalists want the states to decide. It seems that we’ve entered bizarro world. But it goes deeper. Allowing states to set their own emissions standards is a thinly-disguised attempt to impose higher national standards through backdoor means.
