Jonah Goldberg poses a great question: Why not Santorum?
The right is often rebuked for being a party of uncompromising ideological zealots. Terms like extreme right and right-wing Christian are effortlessly used by many. And yet, the Democratic Party elected a man who is arguably one of the most leftist presidents in history who vowed to transform America. Maybe, as suggested by Goldberg's question, right-wing extremists are fairly moderate.
Is there such a thing as the extreme left? Left-wing secularists? Can anyone be too far left?
