Michael Lind in Salon:
Two good essays recently.
1) How conservatives lie about government
... members of the right-wing counterculture are brainwashed — that is the only appropriate term — by the apocalyptic propaganda ground out constantly by the conservative media establishment.
2) Race, liberty and Ron Paul
[this is more about libertarianism than Paul]
Some libertarians concede the legitimacy of government coercion in protecting property rights. But in doing so, these libertarians, like Ron Paul, give up any principled objection to government coercion. They simply want government coercion to be used for some purposes—protecting property rights—and not others—enforcing civil rights.
Re 2), the soundest critique of libertarianism is the Georgist critique, if we're talking "small but not no" right-wing libertarianism.
