2002 Oregon Ballot Measure 23
Measure 23 (2002) was a legislatively referred state statute that would have created a single-payer health care system to provide health care to every person in the U.S. state of Oregon. The proposal would have merged all the various funding streams—personal and employer taxes, federal health programs, and the state workers' compensation system—into a single financing system.
