At NRO, Randy Barnett has some advice for Republicans on how to capture more libertarian voters. His suggestions boil down to:
Oppose intrusions into privacy as vociferously as you would if it had been proposed by the Clinton administration.
Oppose intrusions upon the Bill of Rights more consistently in Congress.
Nominate more libertarian-conservative judges like Clarence Thomas to the courts who care about protecting individual liberty, not just traditionalist-conservative judges like Robert Bork who care most about the "liberty" of the majority to enshrine its preferences into law.
Care about federalism in the Congress.
Care more about the free market.
Stop making snide gratuitous remarks about libertarians. [You reading this, Jonah? -ed.]
Back off Prohibition.
Barnett's got my vote.
