The American Prospect
The American Prospect "was founded in 1990 as an authoritative magazine of liberal ideas, committed to a just society, an enriched democracy, and effective liberal politics. Robert Kuttner, Robert Reich, and Paul Starr launched the magazine initially as a quarterly.
"Since then, the Prospect has grown into a magazine with a paid circulation of 55,000, a special in-depth report in most issues, and a daily Web magazine with more than 300,000 monthly visitors."
