I just looked up some of Blackstone's works, he loved the Monarchy, he wrote "The King is not only incapable of doing wrong, but even of thinking wrong: in him there is no folly or weakness."
I'll stick to the words of people like Madison and Jefferson, I'll even disagree WITH respect toward people like Hamilton or Adams but Blackstone....I'll pass, from what little I've read of that failure so far.
Why do you suppose Blackstone's Commentaries were in every man's hand at the Virginia Ratification Convention?
The same reason a program is in every person's hand at the theatre, because it was handed to them?
He was called a failure by many, he was a Tory, he was in the House of Commons, his contributions are noted as worthy by historians from what little I've read on him but from what I've read so far, I'm not impressed, this is what Jefferson wrote to Madison regarding Blackstone.....
"In the selection of our Law Professor, we must be rigorously attentive to his political principles. You will recollect that before the Revolution, Coke Littleton was the universal elementary book of law students, and a sounder Whig never wrote, nor of profounder learning in the orthodox doctrines of the British constitution, or in what were called English liberties. You remember also that our lawyers were then all Whigs. But when his black-letter text, and uncouth. but cunning learning got out of fashion, and the honeyed Mansfieldism of Blackstone became the students' hornbook, from that moment, that profession (the nursery of our Congress) began to slide into toryism, and nearly all the young brood of lawyers now are of that hue. They suppose themselves, indeed, to be Whigs, because they no longer know what Whigism or republicanism means."
That does not look like a ringing endorsement to me

Of course Judeo-Christians seem to adore him, I gotta look farther into this man.
