Obama and dirty coal

I like the new commercials by www.thisisreality.org which point out the absurdity of the oxymoron "clean coal." Now today I saw an opposition commercial where Obama keeps hyping up "clean coal." I hope the commercial backfires and people will start to question Obama's support of dirty coal. To me, "clean coal" is like saying "clean dirt." Even if they could filter out 100% of the ash, it still gives off CO2, and they still have to remove mountain tops to mine it, messing with the headwaters and destroying ecosystems.
