Why I see biofuels more as an alternative to foreign oil dependence than an environmental issue

This article (link at bottom) is worth everyone on this list considering.
It explains something I think, but much more clearly than I could say it.
I am a moderate conservative who has 3 SVO powered Mercedes Benz 300Ds, not
because I worry about global warming, but because I want to do everything I
can to minimize the U.S.'s dependence on OPEC and our involvement in the
political zoo that is the Middle East.
Personal (and national) freedom is a great back-door for
non-environmentalists to come into the biofuels movement.

Any reactions would be appreciated.
Cheers.
Luke
