Yes. Buchanan went nuts well before 911.
He went over to the left when he and some other ostensible libertarians (who took over FR to some degree like the Strumpettes today but were banned) made common cause with The Nation and their coteries of leftists.
Pat is a genuine conservative. Others have secret motives.
