This guy has single handledly pointed me in the right direction on a number of issues...he takes great exception to the out of control ever expanding federal government, particularly under the current incarnation of 'conservative' 'republican' control, opposes the war in iraq, on obesity, drugs, anti victimless crime, anti homo sexual discrimination, etc...and has a very compelling, hip style of homeboy-ery to his writing.
He often links to like minded libertarians, and is a policy analyst for the libertarian leaning cato institute.
