Perry, BTW, its not normally polite to post comments on personal mail to a list. I thought the list had probably got bored with this nonsense long ago.
The fact that neither of them lives within striking distance of Cato headquarters (O'Rourke lives in New Hampshire) makes your claim ever more interesting.
Being listed as staff in my view makes one a staff member. There have been interesting developments in telecommunications which make it no longer necessary to physically reside where one works. When I was a CERN fellow I was certainly on the payroll of CERN - generally that is what "Fellow" means. If Perry wishes to call me a fool for calling a person listed by the Cato Institute as a member of their "staff" a member of the Cato institute staff then I guess Perry has a different deffinition of "fool";.
