The correct answer is, "What is NONE?"
Stop your exaggerations. You are just wasting bandwidth like your cowardly friend.
And exactly how many times did you claim that Taney was a neighbor of Merryman's, which we now know to be false? Several dozen. In fact you are still claiming it even though you have not the slightest shred of credible evidence and even though it has been shown that Taney and Merryman had residences that were several miles away from each other. Your response to that fact is that their great grandmother's inlaws are buried in the same cemetary!
No, you wrote: "Was Merryman a "personal friend of Taney"? You have provided nothing to refute the claim and I have provided a list of reasons to believe that such was quite likely the case" in post 2173.
Same difference. Face the facts. You lied. You got caught. You have yet to provide one iota of evidence that Chief Justice Taney and John Merryman even knew each other. You and your stablemates have the same tack on everything.
