Or if knowing it, he rejects it?
What is "the center"? There is only one known "center" that yields freedom for the individual without leading to anarchy, and yet order in society without leading to tyranny.
And that center is what the Declaration of Independence says it is:
We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness.
Obama may or may not "move" to the relativistic "center" of a particular moment in history.
But if for political reasons he does move, apart from a conversion to Constitutionalist and Declarationalist thoughtforms, this will be a tactical "adjustment" only.
It will be a move primarily in rhetoric, perhaps with a few policy adjustments. A move that appears to respect -- but actually continues to reject -- what is the true and defining mainstream of the American experiment.
The loyal opposition must oppose Obamaism root and branch. The loyal opposition must articulate and apply with consistency and courage the comprehensive vision that lays out the DNA of liberty -- from worldview to principles to strategies to tactics -- so that in community with God and man, America can once again become a "shining city on a hill."
