The Federalist Society ... and modern Federalism ... is a sham.
Federalism (e.g. Alexander Hamilton, James Madison and John Jay) believed in a strong central government that took a generous interpretation of the powers granted to the federal government for the purposes of governing a nation.
It was anti-Federalism (e.g. Patrick Henry, Samuel Adams and James Monroe) that was suspect/jealous towards federal power and put state/individual concerns and rights above centralized/national interests.
The Federalists begrudgingly agreed to discuss a Bill of Rights after the Constitutional Convention … that came about at the demand of anti-Federalists who distrusted a federal government exercising powers without explicit protection for states and citizens; and stipulated a Bill of Rights as a condition for signing onto a Constitution to supplant the Articles of Confederation.
So, it is ironic that 21st conservatives embrace Federalism, when in fact they are anti-liberal and anti-Federalist in their beliefs and practice.
So, Jonah Goldberg has gotten religion and is prepared to tell partisan hacks and naked ideologues how to be moderate, listen and seek solutions together? If so, good for him.
