Wow, he is good.
I can't find an article written by locke since early 2003. He stopped writing for FrontPageMag.com in February 03 and VDare.com in March 03. He's probably just taking time off or something.
You're right, he is simply amazing in his analysis and knowledge base. Try reading Lowell Ponte over at FrontPAgeMag.com as well. He writes a little bit more powerfully, but doesn't have Locke's depth.
