VDH struggles mightily to identify some theme to make sense out of the ways moral flaws and hypocrisies are played out in the politics of today.
While I admire his effort and enjoy his examples, I think he mostly misses a simple point, the one Lyndon Johnson made about some Central American dictator: "He may be an SOB, but he's our SOB."
It's pure politics, VDH. Politics is not the place to look for moral consistency, moral energy, or intellectual integrity. This is why many believe a degree of sociopathy and narcissism are required in politics.
(As Ace puts it re Sanford: "You can get away with being a bastard, but you can't get away with being a buffoon.")
To the Left, at least, politics is war in which, as they often brag, the ends may justify the means because they like to believe that they are well-intentioned. "By all means necessary.." etc.
I always grant more trust to those who claim to be self-interested - even if they are lying - than to those who claim virtue.
Update: More on public virtue from Rick Moran.
