It is essentially an essay on the republican party killing the programs they used to fight for. Cronon also inked his first ever blog taking a scholarly look at what led to this. It is a good read.
Now the republican party in Wisconsin has filed a information request to get copies of all Cronon's emails from his University accounts in Madison. Does this sound strangely like retaliation? Does it sound like an attempt at silencing a scholar? Does it sound like Senator Joseph McCarthy's tactics. Damn right it does.
