Series 6, about episode 13. King Corn. All the candidates are out in the mid West, and they have to decide whether they are going to back ethanol or not. Its a locally favourable issue. It notionally solved a greenhouse gas problem.. But it doesn't work.
Its an ethical dilemma. Sell out for an easy run in, or stick with your guns? Make an unpopular statement and maybe lose the right to speak into the debate later. Make an untruthful statement and lose the integrity to speak into the debate later.
Do I take the ethanol pledge?
