Nexis reveals some surprising clients at the beginning of Penn and Schoen's career. This is from a 1980 Washington Post profile:
This year Garth is hoping to look after the presidential candidacy of Rep. John B. Anderson (R-Ill.), and Penn & Schoen acknowledge that they'd like to be involved, too. According to others in the business, Penn & Schoen have already done some polling for Anderson. They denied this at first, then said "no comment."
They also had "no comment" on well-informed reports that they tested the water late last year for Gen. Alexander M. Haig. One sources said their poll found that Americans thought Haig might be president some day, but not this year. The general decided not to run.
