Vox populi: Opponents of the 10 percent tax on all poured alcoholic drinks in Allegheny County are ready to put their efforts where their wrath has been. Friends Against Counterproductive Taxation, or FACT, say it's seeking a November referendum that would repeal the very unpopular levy. They'll begin gathering petition signatures in June. At least 25,000 are needed; FACT says it will seek 50,000 signatures just to be safe. Ah, democracy in action.
