The New Yorker has an interesting piece about the American Republicans entitled "The Fall of Conservatism".
I don't necessarily agree with it. Nor would I draw too many parallels with conservatism over here (we've been out of office this past decade, for a start ...)
However, it does underline that in order to succeed, conservatism ultimately needs intellectual verve and purpose. Years of Big Government conservatism end in defeat and retreat - or a McClinton consensus, at best.
All the more reason to read Douglas Murray.
