Heather Cox Richardson, author of a history of the Republican Party, said recently that every politician today, including Barack Obama, would be to the right of President Eisenhower. That’s a bold assertion, but certainly no one would claim that this is your father’s Republican Party. Conservative comes from the Latin for keep, as in maintaining existing institutions. Radical derives from the Latin for root, as in digging things up root and branch. Today’s Republican Party is an aging band of conservatives surrounded by a sea-change of younger radicals bent on getting rid of government. Where does it go from here?
