No capitan. You've only shown that one single purported right winger (who also happens to be a notorious crank that virtually all other right wingers constantly disagree with) has an unfortunate and revealing habit of ending up on the same side of an argument as lots and lots of radical left wingers.
Two of history's most prolific Lincoln praisers are Harry Jaffa and Karl Marx. Marx has a following on the left a million times larger than Jaffa does on the right.
You forget about Rehnquist and his criticism of Taney in the book All the Laws But One. At least I consider him to be politically right of center.
