“Zero Mostel had nothing on Mickey Kaus.”

At least, so said Paul Krugman (from Mickey Kaus, via Glenn Reynolds).
What Krugman is talking about is the play in which the Rhinoceros is a metaphor for fascism, the characters eventually transforming themselves into Rhinos (i.e. fascists).
It’s just Krugman’s cute way of stopping just short of calling Kaus a fascist. (Along with “the rhinoceri running the country.”)
Mostel, of course, was accused of being a communist because of his attendance at Communist Party meetings and “support of Free Earl Browder Movement.”
But I hardly think Krugman was insinuating that Mickey Kaus is a communist.
In any case, Kaus is a little young to have supported the Free Earl Browder! Movement.
I’d say that Krugman has nothing on Zero, but I don’t have a Ph.D. in economics.
