Bernie Sander's "Green New Deal" is Moldy

I hesitate to argue with a politician, as I hesitate to argue with a bratty child.  Most politicians use the arts of rhetorical persuasion at a level not much higher than that a five-year old kicking her heels against the front seat of the car to get another scoop of ice cream.

But surely Bernie Sanders is a mature man?  He studied at Columbia so he must be smart, right?  He's a Jew and a socialist: both groups are generally well-read, by and large?
