The pointless ethanol subsidy

On Tuesday, the Senate rejected a measure that would eliminate
the tax credit given to fuel refiners who use corn-based ethanol. The vote is being reported largely as a signal that Senate
Republicans--who were responsible for most of the "yea" votes--are willing to
consider revenue increases (at least those that come from eliminating tax
breaks for things they never liked to begin with).

Also significant, however, is that most Democrats voted "nay."
Environmental groups oppose corn ethanol, and with good reason: along with
driving up food prices by propping up corn, the biofuel uses more fossil fuels
at the production end than it saves at the pump.

The politics of ethanol are more regional than partisan: if you represent
a state that produces a lot of corn--or have an eye on the White House, the
road to which begins in Iowa--it's hard to be anti-ethanol. Notably, some of
the Republican presidential candidates have come out against ethanol subsidies anyway.
It's past time for President Obama--whose days as a Midwestern legislator and
presidential-primary candidate are behind him--to join them.
