On Conservatives and Libertarians:
Well, I think that the general philosophical divide between Libertarians and conservatives is the conservatives tend to rely on tradition, sort of if it ain’t broke don’t fix it. And if it’s only a little broke, be careful of the fixing you do lest you make the problem worse. conservatives say we have got 2000 at least, maybe 3000, maybe 5000 years’ civilization and let’s learn some lessons from that. Let’s look to the past, see what works, what doesn’t work, and be very careful about changing what we’ve got now lest we change it for the worse. Essentially it’s a rather pessimistic, but rather commonsensical view.
Libertarians tend to take a more rational view of politics and say, "These are some really basic fundamental rules by which we can live. Let’s stick to the rule book. Let’s apply the powers of reason to things like government spending, government programs, projects, and even foreign policy."
