The ad is familiar, I've seen similar since the Cold War. Its a mish mash of environmentalist ravings, FEMA camp hysteria from the left, in a manner to appeal to some on the right. Just one comment -- the reason corn went up and is still up is ethanol -- a left wing enviro hare brained idea.
You forgot to add "that was mandated by W Bush".
For some reason, you seem to consistently "forget" to mention the "rest of the story".
The use of corn for fuel was a gift of the Bush admin to big agriculture. Accept it and embrace it for what it really is, and let's all just try , regardless of our political affiliation, to rid ourselves of this expensive and destructive law.
