J.E. "Bud" Clark is an Oregon businessman who served as Mayor of Portland (1985 - 1993). A populist with little political experience before his mayoral bid, he was one of Portland's most colorful and well-loved political figures.
Before and after his two terms as mayor, Clark was a businessman and restaurateur. He owned the "Goose Hollow Inn", a tavern in Southwest Portland. In 1984 he ran for mayor as one of many candidates opposing mayor Francis J. Ivancie. Clark survived the primary and went on to defeat Ivancie in the general election. He was easily re-elected in 1988.
Clark was known for his eccentricities. He commuted to work by bicycle, and was known for his distinctive cry of "Whoop, Whoop!" He is perhaps best known as the raincoat-wearing model for a poster titled "Expose yourself to art", in which he appeared to ungarb himself to a public statue. As mayor, Clark supervised the growth of mass transit, including the MAX light rail line to Gresham, aided downtown development, and helped begin the process that led to the completion of the Oregon Convention Center.
After his second term, Clark retired from public life and resumed his career as a tavern owner.
