I am familiar with Mr Wills and I'm not buying what he's selling. According to Tribe, no friend of the right, it doesn't obtain.
I will, however, take a look at his work since forewarned is forearmed.
Alas, Tribe's analysis is not available on the internet. I have searched for it. Wills is really quite excellent. I savor that from whatever side it comes from. But that is just me.
