As a reality-based rather than faith-based individual myself, I'm
genuinely delighted to have you post this, Jay. Agrees exactly with
what I hear from scientific colleagues. But just who are the villains
here?

* Farm-subsidy-addicted Midwest voters?

* The politicians they elect?

* Big corporate firms like ADM, who'll gladly accept (and defend)
similar subsidies, even while knowing full well that they're
absolutely undeserved, and while spouting free market rhetoric in
all directions?

* The politicians they bribe?

* The Bush/Cheney administration, with its near-endless record of
suppressing scientific reality in any and every area where they
find the facts inconvenient?

* The voters who elected them?

Lots of villains around -- not all of them politicians

Yes to all including Bush/Cheney but not for the reason you list. I only
blame them for not shouting from the roof tops how stupid the corn for fuel
plan is.
