Ridgeway began his career as a contributor to The New Republic, Ramparts, and The Wall Street Journal. Later, he was co-founder and editor of the political newsletters Mayday, Hard Times and The Elements.
Ridgeway became nationally known when he revealed in The New Republic that General Motors had hired private detectives to tail consumer advocate Ralph Nader in an attempt to dig up information that might discredit him (Nader was behind litigation which challenged the safety of the Chevrolet Corvair). Ridgeway's revelations of the company's snooping and dirty tricks prompted a Senate subcommittee led by Senator Abraham Ribicoff to summon James Roche, president of GM, to explain his company's harassment — and apologize. The incident catapulted auto safety into the public spotlight and helped send Nader's book, Unsafe at Any Speed (1965), to the top of the bestseller lists.
He served as Washington correspondent for The Village Voice where he worked from the mid-1970s until April 2006. Following his departure from the Voice, Ridgeway was hired by Mother Jones to run its Washington DC bureau. On April 13, 2006's Democracy Now! broadcast, Ridgeway told host Amy Goodman that Michael Lacey, the executive editor of the Voice, "killed my column, and he asked me to submit ideas for articles to him one by one, which I did, and which he either ignored or turned down, except in one case...they won't say that I'm fired. I'm supposedly laid off."
