Quick Answer: 2008 Oregon Ballot Measure 55 was a legislatively referred constitutional amendment that lowered the age requirement for state legislators from 21 to 18. It passed on November 4, 2008, with approximately 57% of the vote.

Key Facts

Overview

2008 Oregon Ballot Measure 55 was a legislatively referred constitutional amendment that sought to lower the minimum age requirement for serving in the Oregon State Legislature. Previously, Article III, Section 9 of the Oregon Constitution required legislators to be at least 21 years old upon taking office.

The measure was placed on the ballot by the Oregon Legislative Assembly and approved by voters during the November 4, 2008, general election. Its passage aligned the state legislative age requirement with the federal voting age, which had been lowered to 18 in 1971 under the 26th Amendment to the U.S. Constitution.

How It Works

Measure 55 changed the eligibility criteria for candidates seeking state legislative office in Oregon by adjusting the constitutional age requirement. This allowed younger adults to participate in state-level governance, provided they met other qualifications such as residency and citizenship.

While Measure 55 lowered the bar for state legislators, higher offices in Oregon and at the federal level maintain stricter age limits. For example, the governor must still be at least 30, and U.S. senators must be 30 or older. This reflects differing views on maturity and experience required for various levels of leadership.

Why It Matters

Measure 55 marked a significant shift in youth political inclusion, recognizing that 18-year-olds have civic responsibilities like voting and military service, and should also have the right to run for office. It aimed to encourage greater civic engagement and diversify representation in the state legislature.

By lowering the age floor, Oregon acknowledged that young adults are capable of leadership and deserve a seat at the table where laws affecting their futures are made.
