Pop goes the weasel

ENCOURAGING preliminary ratings for all-liberal Air America in New York have collapsed along with the fledgling radio network’s finances. An unofficial “extrapolation” of Arbitron data released last Friday — which Air America’s hosts crowed about last month but virtually ignored yesterday — showed WLIB’s ratings dropping back to their lowly levels before the net’s April launch.

Arbitron cautions stations and advertisers not to read too much into this interim monthly data — but that didn’t stop Air America star Al Franken from boasting last month that he’d beaten WABC’s Rush Limbaugh among the 25- to 54-year-old listeners chased by radio advertisers.

Being liberal means never remembering what you said yesterday.
