Ethanol as usual

It looks like the late 2010 tax bill will sacrifice revenue to benefit ethanol, which is environmentally unfriendly, http://www.edf.org/page.cfm?tagID=1550, and competes with food production.  If the bill is going to be porked up, Senator Grassley is going to help his people (what else could he do?).   Even as a Democrat, I have admired Senator Grassley as a serious public servant generally, though not for this log-rolling.
