Once upon a time, long ago and in a universe far away (Canada), David Frum was regarded as something not so far from a libertarian himself.
As loathsome as Frum is, he may actually have something to tell the author about the (im)practicality or (im)possibility of the libertarian vision in today's world.
Liberianism presupposes a society of wisdom and virtue. Since we live in a society hooked on freebies, Krum can sadly sleep soundly tonight.
