Crypto-libertarians?

There's been quite a bit of discussion recently as to questions such as Will Crypto-Libertarianism Doom the Republican Party? It's being expressed by some that there is a fear that the libertarian wing of the Republican party will emerge like the socialist wing of the Democratic Party.

What exactly is a Crypto-libertarian? One of the earliest references to that term is found in a 1999 Salon article but it gives no definition.

Gary Reed notes the same lack of definition, on Reason to Freedom:

The term crypto-libertarian pops up all over the politicosphere where everybody uses it but nobody bothers to define it.

Merriam-Webster Online defines "crypto" as: Hidden; not openly avowed or declared; a person who adheres or belongs secretly to a party, sect, or other group.

Meanwhile, a simple modern American definition of libertarian is: "maximum freedom, minimum coercion."

Which implies that a "crypto-libertarian" is a "secret freedom advocate."
